yeah spoiled milk is pretty bad. kind of sticks around for a while.
I held a five dollar bill in my mouth for some reason and it tasted awful.
Food-wise I was sitting at a table with maybe twelve people and tasted someone’s chitterlings (chitlins). The second the bite hit my tongue every instinct told me to get this stuff out of my mouth. I just chewed a couple times and swallowed. No ill effects but man, that was something.
I ate British food once. Do you people have taste buds? 
When I was a little kid, I had to take this antibiotic on a fairly regular basis. It was called Trisulfaminic, and it was horrible. They used to almost have to tie me down and force it down my throat. About half of the time it came right back up, it tasted so awful to me.
Later on, when I first tasted that nasty crap called Bailey’s Irish Cream, it tasted just exactly 100 percent like Trisulfaminic. As if gross sweet alcoholic drinks weren’t disgusting enough! :eek:
(I assume the medicine did not come in pill form, but then I guess little kids get liquid medicine instead of pills because they might choke on pills.)
Ever try stinky tofu? If you walk down a random street in Taiwan some day you might swear that someone has thrown a big dog turd on a hot plate, but no, that’s stinky tofu. And it comes in two varieties: fried and soupy. I tried one bite of the fried stuff once, and it tasted exactly like what it smelled like: fried dog feces. But the worst part was the moist yet bready texture. It’s as if slice of fruitcake were swallowed whole by a dog, and it then passed down the dog’s digestive track and through the lower intestine in more or less unmolested form until it was finally exuded out the other end directly on top of a hot plate.
But that’s not the worst. The worst taste was after an abcess behind my tonsil finally broke. Up to then, one of my tonsils had been swollen to probably three times its normal size, I couldn’t talk, and I was really afraid I might choke to death. A doctor prescribed some antibiotics for it, and they did the trick all right: I woke up the next morning with (1) a feeling of relief that I could finally breathe normally and (2) stark horror at the taste in my mouth. I then leaned out the window and spent five minutes spitting out the large collection of pus that had been collecting in the back of my throat for the past week.
That was nasty.
Rice Dream (rice based pseudo-milk beverage) was vile. The going down was not so bad but the astringent after taste was oh so nasty.
this is stupid…
i was making meatballs for the first time. i was rummaging thru the spice cabinet looking for bread crumbs. i pulled out a plastic tupperware container that looked about right. i dumped it into the mix, and a few minutes later i had a batch of meatballs that looked and smelled great. but when i took a bite…
…i realized somebody had stuck a jar of SAND in the spice cabinet.
needless to say, it tasted a bit gritty
Three brief stories.
When I was wearing contact lenses, I was goofing around in my college dorm and got my lens solution and said “Hey, this stuff is great.” and actually squirted some in my mouth. It was hideous. On a tangent, the first time I tasted seawater, my first thought was “Wow, it really is salty!”
When I was trying to stop my bad habit of biting the skin around the base of my fingernails (don’t ask), I used that bitter chemical that discourages you from biting your fingernails. When I ate some french fries at lunch I was not a happy person. Kinda hard to not get some of that stuff on the fries. Bad, of course, that’s the idea.
Another french fry story. At a restaurant once, I grabbed the “salt” shaker and doused the fries and started in. Tasted kinda funny, but not salty, so I hit 'em again. After a few more bites I realized what was wrong. It was sugar. Not on a scale with year old beer or cat ass goo, but not something I wanted to eat.
This one is a toss up for me. . .it would either be Terpinhydrate, which is the world’s most disgusting cough medicine (works like a charm, though), or the foul concotion known as Green cocktail. For those who don’t know, Green cocktail is what many Emergency Rooms give to patients who are suffering from severe heartburn. I tasted it once, just out of curiosity. Nasty!!
Cement Mixer.
Something that the regulars at my university bar give to gullible first-year suckers during happy hour.
For the uninitiated, a Cement Mixer is one part Baileys to one part lime juice, or thereabouts. Not so bad, you might say, kind of like a lime milkshake? Well, they get the poor sucker to swoosh it around in his/her mouth.
Which makes the Baileys curdle.
Think lime-flavoured, alcoholic spoilt milk… ugh.
Yes, that gullible first-year sucker was me.
I once had a major case of the flu and couldn’t keep anything down. After puking up a cup of tea with sacchrine, I didn’t think anything could taste worse. I was wrong.
If anyone tells you to eat some premium ice cream when you are sick because “it’s too heavy to come up,” DO NOT LISTEN.
Now only are they wrong, but it comes up with a force that will leave your whole body in one big cramp, splash all over the toilet and floor, and leave a taste that lingers for three days will swear you off that particular ice cream forever. If this sounds horrible, the actual experience was about a million times worse.
So I’m not sure that this ranks up with some of the nastier things already posted…but in my experience the vilest taste ever is water…
From the Dead Sea. It is so foul, that even the touch of it upon my lips made me retch. It is because of the extraordinarily high mineral and salt content. YUCK!!!
Believe it or not, my co-worker slipped me a sardine flavored jelly bean. It was colored an indiscrete off-white, not unlike coconut, but the flavor was so truly awful I had to rinse my mouth out with bees. Now, I’m the kind of guy who can stomach a sardine no problem. But when you mix a sugary too-sweet jelly bean, the jelly bean hard-on-the-outside-soft-on-the-inside texture, and the taste of a small ocean fish, you get something akin to the way fish fertilizer smells. Apparently they were a promotional Jelly Belly pack to advertise the upcoming Harry Potter movie. Among other flavors I noticed “booger”. I declined a sample.
Last night, I was eating what racinchikki and I call “Chicken-Os” for dinner. Little precooked 2"-diameter donut-shaped chicken bits, which I thaw out by deep frying. Surprisingly yummy.
But last night, I got a bad one. It was, as racinchikki later gathered from my description, circular, breaded Hell. At first it just tasted like pure salt. Then it got bad. Burned the top layer of tissue off my tongue, etc. I didn’t look at it before eating it, and threw the other half in the trash while spitting out the piece I’d eaten. It was so bad that I spit it out, rinsed my mouth with water for several minutes, brushed my teeth, then threw up. I still don’t know what was wrong with it. What does rotten chicken taste like? Or maybe it was a deep-fried feather. I should sue Bo Pilgrim for emotional distress. I don’t think I’ll ever be able to eat those again.
Compared to that, gasoline, brake fluid, and teeth-braces-glue (I’ve tasted all of the above, though not at the same time) are like [insert favorite good taste here].
A distant second: Once, while eating Cheetos, I got what I thought was a large, round Cheeto. It was actually a solid lump of the powdery Cheeto coating. Not good. It was about the same texture as the Bad Chicken-O, now that I think about it. :shudder:
Oh my! I had tears rolling down my face from laughing so hard at that one!! I think the neighbors heard me hooting away in here.
Pleasestop!! My sides are aching!
(Hand feebly coming up from under computer desk.) Fo-Ti!!! I can’t stand it!!
(Feebly, from still under the desk, 'lutefisk … I think I just broke a rib.)
(Now dying under the desk in hysterical spasms of laughter) '“I thought it went in the other end.”
End of the posts! I’m saved! I’ve not laughed so hard in years! 
Uni, by any other name. Sea urchin roe. Yes, the worst stuff I ever put in my mouth, at least that was supposed to be food. I’ve never put anything in my mouth that was truly gross, like dirt or poop or such. And other than some unmentionable body parts…
But as far as food goes, that was probably the nastiest thing I tried. And I was being completely open minded about it.
MOODTOBESTEWED
That is just fucking gross…
I think you win.
Grapefruit. Hands down.
Anti-perspirant runs at a very distant second. The problem with accidentally getting that stuff in your mouth is that it dries up your saliva instantly, so you can’t even spit it out. The only solution is to drink water immediately.
Still, I’d rather have a diet that consists of nothing but anti-perspirant for the rest of my life than have a single bite of grapefruit. The evil fruit must be destroyed.
As a side note: nothing is more annoying than someone who chimes in “but… but… but… they’re ok if you put a lot of sugar on them.” Ugh. Sugar? Let me get this straight: you have perfectly good, delicious, happiness-inducing sugar, and you want to pollute it with freaking GRAPEFRUIT? Dammit, just spare yourself the trouble, and eat the sugar.
I took a bite out of some weird cookie in Sweden. It looked like a Halloween cookie, with a pumpkin face and a chocolate top. But it was in the summer. Maybe they had it sitting in a warehouse for a few months. It tasted like some toilet cleaning liquid, only worse.
Goldenseal.
My brother was unemployed and a pot-smoker (imagine) and heard it was a good way to purge your system so that you could pass a piss test. He bought a vial of the stuff in a liquid form, tried it once, and couldn’t stand it. Being the li’l herbalist that I am, I told him I’d take it off his hands, since I heard it was good for all kinds of infections.
Next time I started to come down with a cold I took a dropperful of the stuff; he was right. He compared the flavor to if you went to a parking lot and licked the black spot in a parking space where all the oil drips. It was earthy and metallic, and one of those tastes that seems to permeate your whole head as soon as a drop touches your tongue.
It does knock out colds, though…
I’ll second Big Sam’s mention of paintball paint as being a pretty unsavory flavor. The echinacea capsule that I swallowed on an empty stomach was pretty friggin’ bad when I burped 20 minutes later, too.
My truly horrid, I’m-gonna-puke in-mouth experiences have related to nasty texture, more than vile taste. The two instances I can specifically recall wondering if I’d get the mouthful down without redecorating the table involved: (1) scrambled egg with a large chunk of congealed white; and (2) raw fish of some sort at a Korean restaurant.
People eat this stuff all the time, but really feared I was about to hurl.
