I always want to like new cuisines, but lots of odors turn me off.
I went with friends to a Thai diner, and when they unwrapped a foil-covered fish I nearly threw up. Even smelling the other sauces made me nauseous, so I said I had diarrhea and just left.
I know they will want to go back, but I’m planning to play deaf to that and just never say yes or no.
I fourth Star Wars. My friends are horrified. Apparently I may no longer call myself a geek. 
ketchup. Salt and vinegar chips are a beautiful thing, but ketchup? Bleagh.
fried seafood. Don’t get me wrong, I love seafood. Just not the stuff that’s breaded and swimming in oil.
Heh, so did I – on a first date, no less. It didn’t bode well for the rest of the relationship. However, I don’t remember particularly wanting to like The Matrix, so I don’t know if it counts for this thread.
I do feel bad about the fact that I don’t really “get” instrumental music of any genre; much of it is not bad as background music, but it has to have lyrics for me to really like it.
Chicken smells so good! but tastes so bad! I wish I liked it. And coffee , i hate that stuff too.
Food, I’m a HUGE picky eater. It’s a pain in the ass to me. It’s an embarrassment to people that try to cook for me. It limits where I can eat. And what’s worse is so many people think you’re doing it just to gain attention or something.
Carnivale, could they have slowed the pace down just a little more? Could they have had one more obscure conversation? I really wanted to like that show.
Coffee, is crap.
The sequels to Dune.
Yeah, anime is a big one for me, I’m surprised I didn’t put it the OP.
The thing is, I’m really good at looking beyond the inane (and insane) Japanese sillliness in RPGs and other anime-based video games. But for some reason, when its played out for me in movie form, every stupid, non-sensical comic relief and amorphous soul-sucking giant alien monster just makes me roll my eyes and turn it off.
Really, I get how it could be artistic, and sometimes deep, but what the hell kind of substances do you have to consume to come up with this crap, anyway?
Hmmm, where do I start?
I don’t like Seinfeld, or the Simpsons, and I’ve never seen Sex and the City.
I don’t like ketchup, mayo, mustard, etc. I like my stuff plain, damnit! 
I don’t like tomatos, or tomato based sauces, pickles, ranch dressing, or raw onions (even cooked are a little hard to handle)
I don’t like rap (with a few, rare, exceptions) or most of the other crap they play on radio stations anymore.
Same here. And noone seems to like just making me a cheese sandwich or something. They seem to feel guilty for not spending ages cooking me something!
SUVs - If you live in a mountainous region, or out in the woods somewhere, sure you may need an SUV. But the millions of people that buy SUVs to bop around to the malls in the suburbs … what’s the point? It all seems like a “monkey see, monkey do” thing to me.
Watching sports-nothing is more boring than having to sit and watch baseball, football, racing, basketball, fishing, bicycling etc. Whether on TV or in person I find it to be incredibly, painfully dull. Same with sports statistics and fantasy leagues, I just can’t even fake interest in them when they are brought up.
Loud Music-I do enjoy going out to hear bands, dance or have a drink with friends. Unfotunately so many places have the music almost painfully loud so you cannot have any sort of conversation.
Comics-I’ve tried to read them when I was younger but never got into them. I liked Mad Magazine as a kid but never understood the appeal of comic books.
Anime-No clue as to its appeal.
Cars-they all look alike to me and when they announce the new models, the look just like every other car/truck/SUV whatever. I also could not care less how much horse power it has, if it can go 0-60 in .3 seconds or how much nicer it is than my home. Just get me where I need to go efficiently and reliably is all I ask for.
Online games-I am not interested in playing chess, football or other video games with people on the other side of the country. I’m also not big on video games in general. I do have a couple, but and can go for long stretches without touching them. I probably won’t get any more.
I heard all about Princess Mononoke and how great and life-changing it was. So I finally sat down and watched it and my net reaction was: “HUH? This plot makes no sense.” And I’ve seen plenty of the other “good stuff” too, and my reaction is either “Huh?” or “This is dumb.”
I’m fine with video games and stuff too.
Though like with jazz, I think the fans do quite a bit to turn me off.
I was going to be annoyed at all you jazz-haters, but frankly there’s so much bad jazz around these days that I can’t say I blame you. Still, give me a Sarah Vaughan recording and I’m a happy, happy man.
Fortunately for my bank account, I dislike a lot of luxury foods:
Champagne gives me headaches, as does any sparkling wine. Plus I just don’t like the taste.
Caviar I don’t get – it’s fish-flavored goo. I like sushi and sashimi and have even eaten raw scallops, but caviar is just plain nasty. Lobster is not quite as bad, but it’s not worth either the price nor the effort to eat. Give me a nice salmon fillet any day.
And I don’t like steak very much either. About every six months or so I crave one and make it myself, but otherwise I just don’t even want to think about it.
Another non-coffee drinker here, compensated for by a high level of tea consumption (but only good tea – Lipton is undrinkable swill). Similarly, diet soda of any sort is vile spew.
Other non-food things I can’t abide: rock concerts, reality television, Titanic, Britney Spears, Internet access on my mobile phone, modern fashion, getting drunk, sports cars, televised baseball, (American) football in any form, breast implants, and pretty much every other part of popular culture. I’m officially a fuddy-duddy.
Dune.
I love to read, I like the genre, everyone else glorifies it, I should enjoy this, right? Just can’t get into it, at all. I’ve tried a few times, figuring maybe I just wasn’t in the right mode or something, nope still bores me. I hate feeling like I’m just missing the glaringly obvious boat there, but I just don’t dig it.
Beer.
I like alcohol, mixed drinks or all the frou frou girly beers like Mike’s hard lemonade and Schmirnoff Ice, but cannot develop any appreciation of beer. Once visited a semi-famous pub in Bruge Belgium that had an outrageous menu of ales and beers, my friends were ecstatic and I was begging for a simple soda or juice.
Professional sports. Growing up in a blue collar town like Buffalo, culture tends to be bipolar, running either on the upper end of highbrow (world-class symphony performances, art galleries filled with works by the masters, lectures by postmodern philosophers, and so on) or extremely lowbrow (Chinese auctions, meat raffles, volunteer fire department picnics and Monte Carlo nights, modding 1960s-era muscle cars, mullet rock, and the like).
The lowbrow end predominates, and the majority of Buffalonians being sports fanatics. It’s not just the Bills and Sabres; it’s watching ESPN 2 to see football games between small, obscure Midwestern colleges, or taking baseball statistic geekdom to a higher level. I’ve always wanted to be a sports fan, and I understand the basic rules of most popular North American sports for the most part. Still, though, I just can’t get into a game; I could care less who wins or loses, and I don’t understand the strategy. I have no clue what John Madden or Don Cherry is talking about. I don’t know what “offsides” means in any sport.
Classical music. It sounds nice, and it seems intricate and well-thought out. My impression is that to be a classical music fan, you have to have a golden ear. If I hear something by … oh, Mozart, I can’t tell whether it’s the Buffalo Philharmonic or the London Symphony Orchestra playing it, and whether one rendition is different than another. Apparently, it really matters. Classical music fans seem to anaylize a performance with an intensity matched only by … well, John Madden discussing a split inverse straight-t passplay backfield formation versus a 4-3 short yardage rollout special teams defense.
Another one left cold by Star Wars. I tried to watch it twice on television, and fell asleep both times.
I have not seen LOTR, or The Matrix.
The way the people here feel about Seinfeld (which I think is a great show) is how I feel about Sex in (and?) the City. The whole show seems to just be a vehicle for nasty, self-centred people to talk about themselves. No thanks.
Peanut butter is evil.
I actively loathe anything even remotely to do with Disney, even the “classic” animated movies we are supposed to love (and I tried to like them). Wile. E. Coyote, Marvin the Martian and Daffy Duck - now there are some fine cartoon characters, not those syrupy, doe-eyed, flawless Disney characters. Disney almost got it right with Donald Duck, but that stupid voice and cutesy sailor suit make even him sickeningly sugary. I especially loathe the way Disney has cutesified and dumbed down the works of others - A. A. Milne, and the like.
Harley Davidson motorcycles. Noisy and pretentious, and according to bikers I know, they handle like a newborn camel on rollerskates, and are about as reliable, with their 1950s tech.
Blue cheese. The tiniest taste of this vile stuff will invade my nostrils and stay there for the whole day.
Diet drinks. That aspartame stuff is nothing like sugar. It is waaay too sweet, and it gives me a headache.
Olives. I love olive oil and cook with it every chance I get. But olives? Blech. The taste is all wrong, and the texture is nasty.
Wine. I love the idea, the history, the whole feel of it. The only kind of wine I can bear drinking? Boone Hill’s, and I wonder why people are so down on it. Most alcohol, actually, tastes icky to me. My idea of enjoying a beer is sipping about half a bottle over an hour and a half.
Coffee. Same as the others. Why would I want to drink something hot enough to boil my soft palate and bitter enough to kill all the beneficial bacteria in my mouth? Yuck! (Mocha, however, is just fine.)
Beer: I hate the taste. It’s the hops, I think.
Coffee: Bitter, bitter stuff. If I put enough stuff in it to make it drinkable, I may as well have ordered the hot chocolate or a Dr Pepper.
Lobster: Meh
Skiing: You want me to strap myself to these two oversized rulers and propel myself down this mountain? What was your mother smoking when you were concieved?
Anime: Meh. I don’t see the big deal. Most of the stuff I have been convinced to sit down at watch left me going “What the hell was that?”
Slash: I have friends who are excellent writers that write slash. They love it. It seems damn near everybody I know does. But I don’t. I am not homophobic. I’m bisexual, and so is my daughter. I just don’t like slash. Any of it. I think Lucy Lawless is hot, but I am not interested in Xena/Gabby slash. Legolas and Arogorn are smoking hot. L/A slash? Get the fuck away from me.
Buffy the Vampire Slayer: I tried to like it. I wanted to like it. I hate Sarah Michelle Geller.
I have it on good authority that my mother makes The Best:
Fruit Salad
Banana Pudding
Pumpkin Pie
Cherry Cheesecake
Mincemeat
And I won’t eat any of them.
Sushi: No thanks. Yuck. Patooie!
I also want nothing to do with: Olives, Squid, Rap-especially that Gansta crap, Reality Shows, The Simpsons, Mushrooms, Seinfield, Friends, Yappy Lap Dogs, Brittany Spears or any of her ilk, the Rolling Stones, The Who, Punk music, Tool, Radiohead, Marilyn Manson, anything remotely resembling Springer, and I’m sure there’s a lot more because I’m a bitter middle aged woman.
My dislikes are few, but strong.
Beer and hard liquor. Wine is fine from time to time, champagne at a celebration suits, but I cannot abide any beer nor any other spirits. Sherry (which is technically a wine, I know) brandy, rum, vodka, bourbon, scotch, whiskey, tequila, schnapps of any kind, they all make me ill just to smell, let alone drink.
Meat. If it had a face and/or a mother, I can’t eat it, whether it walked, flew or swam in life. I’ve tried beef, pork, chicken, turkey and lamb and shrimp, salmon, flounder, tilapia and crab. I found them all disgusting. I didn’t like the flavors, I didn’t like the textures, I didn’t like how I felt when I ate them.
Chocolate Foods. Chocolate candy is fabulous. Even candy bars, like Snickers or Three Musketeers which are only part chocolate are great. But chocolate cake, brownies, chocolate in cookies (Oreos or chocolate chip or something like Milanos) or chocolate sauces over ice cream or whatnot? Nope. Chocolate to me should be a food in and of itself, not a flavor.
Democrat Party/liberal Politics. I’m an African-American who moved from the impoverished rural south to major northeast urban areas, all Dem strongholds. But despite my indoctrination with liberal ideology from the cradle, I find them repugnant, and have been a Republican since I first registered to vote back in 1978. I have voted for Dems (and independents, Libertarians and even a Green for a local office) but in general I cannot accept them, their policies, their ideas or their tactics.
Pro Basketball. College hoops are a long time hobby, but once they graduate to the overinflated salaries and even more overinflated egos of the NBA, I’m turned off entirely, to the point that I don’t even have a nominally favorite team.
Written Science Fiction. I love SciFi movies and television. But the idea of sitting down and reading anything of that sort just bores me to tears.
Anime. I. Just. Don’t. Get. The. Appeal. It does nothing for me. I think it’s silly and actually, rather irritating.
Beer. Just too damn bitter for me, but the Germans have some nice heavy beers that are okay, and malt liquor is fine as well. Sometimes I’ll do what German bartenders will do for GI’s that find their beers to bitter: fill it halfway with Coke. It’s not bad, really. I much prefer a good, dry red wine.
Cherries. I like most fruits, but there is something about cherries that give me the equivalent of piss shivers every time I accidently bite into one.
Condoms. I know that they’re necessary sometimes for birth control, and for prevention of diseases. But I just can’t get into it when wearing one. It ruins the entire experience for me. I don’t think I’ve ever climaxed with one on. Bleh.
Hard candy. Don’t like any sort of this candy. When I used to go trick or treating I would seperate them all out and put them in a candy dish in my house. I prefer something I can sink my my teeth into.
I’m also not a coffee drinker, but I like mochas and cappucinos with flavored syrups.
I have actually learned to overcome a lot of my food and drink dislikes with perserverence, e.g
Beer- when I lived in England, I used to drink alchopops when
I went out. When I first moved to Hungary they didn’t exist, and spirits were expensive. Wine gives me a massive headache after a few glasses, so I kinda trained myself to like beer (and now alchopops taste like alcholic sugar water)
Same with gin- my whole family plus my b.f love the stuff, and I always felt very left out as when they all used to have pre-dinner g and t’s. Plus I always liked it in theory- such a crisp, clean taste, in practise ick! too sour. But I had a sort of epiphany last time I was home and my brother mixed me a g and t- now I love the stuff as an occassional treat.
I have had several similar experiences with other foodstuffs except:
Broad beans- I love almost every other type of vegetable, and the number of foods I don’t like of ANY kind are very few and far between, but I HATE broad beans. The rest of my family get so excited about them- fresh ones out of my Grandma’s garden, all smothered in garlicky butter- look sooo good ummm…urgh!, taste GROSS!
I also have no time for coke, or fizzy drinks of any kind really- they don’t quench my thirst, and I can taste all those spoonfuls of sugar-give me a nice glass of apple juice instead any day.
As for cultural dislikes, there are none that I would change- because of course, my taste is without flaw, and everyone else is wrong…
