I will fourth or fifth sea urchin. I hear it’s supposed to taste better if it’s really fresh, but the one I had at a party in the middle part of Japan (e.g. as far away from the sea as possible) was disgustingly bitter. It’s not just that it tasted bad, it tasted wrong. Like something that no human should be eating. :eek:
Not supposed to be eaten… I once accidentally ate a fly that landed on my hamburger. That was pretty disgusting. Tasted a lot like uni, actually. 
Did it, or did it not, taste like raw, horrible death?
Oh come now, it’s not that bad. Females aren’t, anyway, who have an infinitely more palatable taste than men.
Oh, and in middle school I found the taste of caviar pretty awful. Being a vegetarian these days I won’t have the opportunity to re-evaluate it with a better palate.
Okay – I have to object to this one. I grew up with C. Howard’s violet gum and violet mints, and I deny any “soapy” taste to them. They do taste “perfumy”, since most people associate violet with perfume, and not something you’d eat. But I do love the violet mints. I have a pack open on my dresser right now.
I think you did get some bad lychee - lychee is actually quite nice; a mild, pleasant-tasting fruit. I’d understand if you never wanted to try it again, though - I’m sure mussels are quite lovely, but after having a bad one, I’m not too keen on them, either.
It did. What you see etc. It was absolutely foul and horrible - and I was so drunk at the time that I shouldn’t have been able to taste anything at all. A bizarre night, really. A friend of mine ate The Love Song of J. Alfred Prufock to get the snake taste out of his mouth, I think.
Heh, a friend of mine drank something called “Jew’s Ear Juice” in Hong Kong. Apparently, a quite disgusting mushroom compound. 
Count me in as perhaps the only (other?) person on the planet who actually likes Thrills.
Lychee tastes too flowery to me. Looks pretty, the first bite is always “Wow, I must’ve just had a bad one last ti-bleghghhhwharbblee!”
Similarily, I used to have a thing for room temperture sodas and I had set my coke can down next to my brother’s spit receptacle. I did notice as I was taking a swig that it weighed more, but just a fraction of a second too late.
Jeppson’s Malört. (Wiki, taste test.) The taste is so amazingly bitter that there’s actually a Flickr group dedicated to the faces people make when they drink it.
It took me weeks to finish the whole bottle.
Ah, Chicago’s very own Malort. I was actually a bit let down when I first gave my girlfriend a drink of it – she actually liked it from the first sip. I was hoping for the usual face-scrunching reaction. It is, indeed, perhaps the most bitter substance you’ll ever taste, being flavored with wormwood. But it’s also a popular drink in my family (all of who like very bitter flavors.)
I bought a package of Krusteaz Lemon Bar mix as I was too lazy to make lemon bars from scratch. They came out of the oven with this weird rank smell, I can only describe it as “barn-like”. Of course we tasted them! Yup, tasted exactly like a nice, manure covered barn floor.
Very odd, a packaged mix going bad like that. Krusteaz said it might have been improperly stored in the heat and turned rancid.
1 (meant to be eaten): some weird glazed fish thing in China - don’t know what it was, but it was covered in this slimy sticky sauce that was both too sweet and had a weird sickening pungent thing going on. It was also served whole and had a weird texture.
2 (not meant): One more vote for beer can with cig butts in it. So not cool.
Tried to figure out what the difference between Nestley’s chocolate mix and Hershey’s Coco.
Raw sewage, standing on a ladder looking for leaking pipe, it broke.
2a. Not me, friend got the munchies after drinking/smoking and ate half a bag of catfish cheese bait. He only stopped eating it because we took it away.
OK, just to establish credentials… I actually like a lot of things that have been listed thus far. My favorite pizza is anchovy, caper and olive. I enjoy very spicy foods as well, and will happily consume peppers that most people couldn’t tolerate. Sea urchin, eh, not my favorite, but OK. Having said that…
I forget the name…there’s a pub in San Mateo, California popular with British expats and other beer snobs. They have a “Habanero Burger” which is just ridiculously painful. I took one bite and was in AGONY. No amount of beer or water could quench the horrible, searing pain, and I eventually had to go in the bathroom…not to use the facilities, but just to curl up on the floor and sob in privacy. Not recommended.
In college I worked in a fast food restaurant which served sesame chicken nuggets…quite yummy, especially after a few beers. One night I was hanging out with some co-workers at their house and was offered a nugget which had been brought home from work. They neglected to mention that it had been brought home three weeks ago, and had been at room temperature since. Fortunately, it had solidified so that my teeth barely made a dent, but still…I get nauseated remembering the awful, putrid, rotten taste of death now, over twenty years later. I really tried to puke on the guy’s bedspread in revenge, but could only manage several minutes of convulsive dry heaves.
Dr Pepper Cherry. Would gladly eat a durian to get rid of THAT taste.
Semen. Though preferable to the aforementioned Dr Pepper.
Another vote for kimchi (sp?)
Vomit. Someone else’s vomit. She was very drunk and I was kissing her and she threw up in her mouth a little and…well, you get the picture. We subsequently married, so I don’t think it was the fact that she was kissing me that made her throw up…
Maybe it’s something to do with the arctic environment but the talk of lutefisk and decomposed shark reminds me of what the Inuit here in Alaska (and not always just the Inuit for there are some Interior tribes serve this as well) also…uh…create. It’s called “stinky fish heads” and it is precisely that. Fish heads which are left to decompose for several weeks. I’ve never had any. I don’t intend to ever have any. But I know folks who swear by it (and a few who swear because of it).
The Interior natives have a couple delicacies…stewed moose nose (the bulbous portion of a moose’s “muzzle”) and porcupine. I’ve also heard they can be tasty but again, I think I’ll stick to my escargot. That’s about as adventurous as I get unless you want to count Mickey D’s, which can be rather disgusting when you really think about it.
That and 100% ethanol. Burned the inside of my mouth terribly. Really, mouth pipetting is not a great thing to let your students do.
