Chicken flavored pet vitamins are up there… probably buttermilk though

Taste? Probably expired milk. I didn't sniff check as a kid. A mistake you only make once.

Most disturbing to me even though it tasted okay? I had one of those cardboard cartons lined internally with plastic/aluminium so you couldn't see inside. Well within best by date. I poured a glass, chugged it. Hot summer day. Decided, eh, a little more why not. A giant gloopy growth plopped out into my glass. I retched.

Mother of Vinegar I assumed? Not sure.

I got some of that pre period goop in me once. I would say that turnabout was fair play for a dude but I don't like blowies so I just got gooped for nuthin

Yeah I fuckin swallowed it, I'm not bitch made

Cambozola. The descriptions I've read about it are entirely unlike the one I tried. It was intensely foul.

Natto. Japanese fermented bean paste. Slimy and tastes like rotten cabbage.

I've been on crutches more than once, so pick an item.

My girlfriend-at-the-time's dirty, dirty ass. Thought it would be like in my fantasies, where it tastes like candyfloss and smells like a Yankee candle. Nope. Shit. Just shit.

If you're curious, shit tastes exactly as it smells. I wish I didn’t know that. Although I'm happy that now you, too, know that.

And she had the nerve to dump me later. I deserve a Nobel peace prize for not recoiling in horror and instead just powering through in silence like a fucking GENTLEMAN.

On the bright side, it became a great way to ensure future partners were cognisant of the issue. I'd drop it into the usual "what was your ex like?" gossip sessions that come with new relationships. It's like saying "please wash your various holes if I'm gonna go rooting around in them like an ant-fiending aardvark" without actually saying it. A cautionary fable from days of yore to guide the next generation.

P.S. I'm still pro-anilingus. Just... clean the fuckin' thing first. I don't need to be picking dingleberries from between my teeth, thanks.

Slug.

When I was small I left my kazoo outside in the yard, and then when I went to play it the next day, I learned the hard way what slugs taste like.

They’re bitter.

A particular man's penis. I realized too late that he didn't routinely clean under his foreskin.

Fast food

Gasoline. Had to siphon, did it wrong, mouthful of gas.

Cat treat. Ate it on a dare. It was fucking foul. 0/10.

An oyster

The town I grew up in is famous for them, we even learned about them in school but I'd never tried one

Finally decided to just before I moved away for university and eugh, salty mucus-y blob, had to spit it out again, poor lil guy

One time I got the bright idea to siphon the water out of my ~50gal aquatic turtle tank for some long overdue cleaning. I anchored one end of a water hose at the bottom of the tank and strung the other end out into the yard and proceeded to start the siphoning process with my mouth. Got force fed a giant gulp of whatever got sucked off the bottom of the tank.

I've put some nasty shit in my mouth since then and nothing comes close.

Prolly a spider that had crawled into my fountain drink straw or viewed another way when I vomited up a metronidazole pill that I had worked very very hard to swallow without tasting and immediately vomited again as a result. If you're unfamiliar it's the antibiotic pill that makes you taste metal.

I was passing through Montevideo, Uruguay, and me and some folks at the hostel I was staying at were out trying a local restaurant. The guy who owned the place saw we were tourists and said he wanted to treat us to a local specialty, and so brought out... something. It was something like animal bits, chunks of fat, and who knows what else all suspended in a hard gelatin. It was truly vile, and I swear it had bits of hair in it as well. To be polite we all tried a small bit, and then got the heck out of there as quick as we could.

To this day I can't tell if he was sincere, or if he really hated tourists and gave us the contents of his dish trap. Googling has turned up nothing, but thankfully our politeness didn't extend to actually finishing the awful thing.

pig intestine from a chinese restaurant, a meeting of the 'adventurous eaters meetup'. consistency of a mouthful of snot.

Liver. Onions were fine, but what kinda sicko likes to eat liver? ~~Just knowing it's where urine is filtered turns me off, but I was made to eat it as a kid before I learned that.~~ Man, my brain is turning to shit as I age.

When I was around 3 or 4 y/o, a neighbour kid managed to convince me to take a bite of a dried dog shit.

I don't remember what he'd said that convinced me, I just remember the laughter when I actually did it... I wasn't the brightest kid, but very curious and gullible.

The Elvis. The sandwich American rock singer Elvis Presley made famous. Peanut butter, banana, and bacon. Grilled like a grilled cheese sandwich.

Addendum: I am allergic to peanut butter. I got ahold of a soy-based alternative called Wowbutter, and people who are not allergic tell me they nailed the taste, but the aftertaste is kinda not good. So, the first thing I did was shove a whole teaspoon-full of it in my mouth. My brain goes "you dumb fuck, you're gonna die," but I didn't, because it wasn't toxic. So I went and tried everything made with peanut butter (BTW, strawberry > grape for PB&Js), including the Elvis. A lot of it was kinda gross. I guess if you were raised on peanut butter, maybe, I can see it, but I didn't think the experience was anything special. Not when Nutella exists... which I also can't have. But then there's Biscoff spread, which is non-toxic, apparently it's also vegan (wouldn't peanut butter be, too?), and it's ten billion percent better than all that other shit. Though, you would be absolutely right in saying I've never had real peanut butter, or your favourite variety of it.

When I was like 8, I was playing with my remote control car, one with a battery pack you had to unplug from the car and use a special charger in the wall. After I recharged it, and was getting ready to drive it around, i noticed I had what I thought was leftover chocolate on my finger. I licked the drop off my finger and immediately realized it was battery acid or some residue from the battery, it was the worst taste ever.

PVC pipe glue. Don’t ask.
