Oyster. Anything with the consistency of snot that you're supposed to swallow without chewing isn't food. I can make my own salt water that tastes much less disgusting.
Venison can be good if it's properly butchered and stored. It so often isn't though. People will shoot a deer then leave it to hang for a day in 50-60 degree weather. Just gross.
Bears are too greasy. And they're too smart, eating them is just bad karma.
A lot of game meat can be good, people just have no clue what to do with the processing side of it. They'll spend thousands of dollars buying the most ridiculous gear to kill the damn thing, and then just fail at butchering and preserving. Hunting is the easy part.

I can't speak to crocodile, but I have eaten a lot of gator. If it's not prepared properly it goes from tasting like water chicken to tasting like swamp thang.
You said not lamb but lamb. Nothing will ever taste worse than the lamb steak I had from a high end Brazilian churrascaria once. It straight up had the taste and texture of poop. Thinking about it makes me gag.
That's also where I learned how much I hate filet mignon
Uni (sea urchin) at a Japanese restaurant. It was like cold fishy jelly. Although I'm told that fresh uni is different. Not gonna try it again unless someone else at the table orders it.
Perch are good if you fry them right. But I live up north where the water stays cooler, I think it makes the fish taste better. You go down south and anything you catch just tastes like swamp.
I always wanted to try catfish, and there was a restaurant I really like that does everything else really well, so I tried it and... Nah. Tasted like fishy dirt meat. I've had bad duck, too.
I'm not a fish-eater in general, but I am an avid fisherman (I just catch them, the wife eats them,) so I've heard a lot of stories from my fellow anglers (which should, of course, be taken with a grain of salt, there's a reason they're called "fish stories")
There is a persistent rumor I've heard that some people will take catfish and other bottom-feeders like carp home alive to let them swim around in a bathtub of clean water for a day or two to sort of flush all of the mud and everything out of their system before cleaning and cooking them
Oh, man... I'm not a huge fish eater, but I can honestly say some of the best fish fry days I remember were when we couldn't catch enough walleye to feed everyone. Someone would take a few of us kids out to have us catch a couple dozen perch. Beer battered and fried in a cast iron pan over an open campfire? Perch are effing delicious.
Here I see a lot of people who have been served badly prepared game. For any meat that tastes too gamey, if you're not sure how to prepare it, there are some tricks that work pretty much everytime:
Make an infusion of ginger by boiling it for half an hour. Lot of ginger, the water must taste spicy. Then soak the meat in it overnight. It won't really live a gingery taste in the meat, so it's good for most preparations.
Don't roast, but braise. Red wine, juniper berries, rosemary, cloves, bayleaves, and laurel are good with most wild animals and musky meats: deer, wild boar, mutton, rock goat, etc etc. Sheepmeat and goatmeat can also go with a lot of cumin, turmeric, chili, cinnamon and cardamom, if you want a more central Asian vibe.
Presuming you mean meat I consistently dislike no matter if it's well prepared or in good condition: None. I would say beef and chicken but those were isolated instances and you removed them as options too.
Then... I don't know, every time I tried something else it turned out to be good. Once I had a codfish that wasn't well prepared. It was tough like a shoe sole and full of bones. But it didn't taste terrible, so I'm not sure if it's a suitable option.
Not many, I've had crickets, ants, mealworms, venison, kangaroo, I think that's it for unusual. Not sure if things like duck and eel make it to the exotic list for you. I've had kangaroo more times than I've had eel though, probably just because of location.
Carp. Had it in poland. The toughest fish meat I've ever had, riddled with tiny annoying bones. Tastes a bit like discount supermarket proscuitto... not exactly horrible, but it was so much effort to eat the damn thing to boot
I had wild rabbit at a restaurant where the chef cooked meat he hunted himself. It had a really strong flavour I couldn't quite name. I could see other people enjoying it, but not me personally.
There was a sign that warned diners to watch out for free prizes (shotgun pellets). I didn't come across any, but I was wary of chewing too hard in case I did.
Irony of ironies is that I love fishing. Luckily anything I catch worth keeping my wife is more than happy to eat.
People always tell me that good fish shouldn't taste/smell fishy. I retort that I suppose good beef shouldn't be beefy either.
I'm willing to hear people out, try different fish prepared in different ways, still haven't found one that I liked, at best they're mostly tolerable.
I've figured out that I generally tend to enjoy freshwater fish over saltwater. If I catch a couple nice trout I'll eat that for dinner with my wife instead of having to make a separate dish for myself, I won't hate it, but I won't like it either and I'd probably rather have a hot dog.
And I like raw fish better than cooked.
I might actually kind of like raw oysters, but they are in no way worth the cost.
Lox isn't bad, but I'd prefer just about anything else over it.
There are a couple fish-based products out there that are so far removed from fish that they're hardly worth mentioning for the purposes of this comment that I do enjoy, like Worcestershire sauce and Asian fish sauces, katsuobushi, Caesar dressing, Crab Rangoon (let's be real, you could probably leave the crab or "krab" out of most takeout rangoons and it wouldn't change much) some Japanese fish cakes, etc.
The absolute worst is shrimp though. Nothing about shrimp is appealing to me, the taste, smell and especially the texture are all pretty repulsive.
I'm not otherwise a guy with a lot of food hangups and consider myself a pretty adventurous eater. Weird tastes, textures, bizarre fermented stuff, strange meats, etc. are all generally OK in my book, there's not many other foods out there that I don't enjoy. In my house right now I have some double salt salmiak licorice, a bottle of Malört, a wide selection of hot sauces going up to around 1 million scoville, I'm pretty sure I have both Vegemite and marmite somewhere in my fridge, some very peaty scotches, and plenty of other very divisive foodstuffs that I enjoy.
I have tentative plans to visit Iceland next year, so I'll probably end up torturing myself with some hákarl at some point. And I don't intend to seek it out, but if it happens to be offered to me for free somewhere I may consider trying whale, which I suppose is technically seafood.
Any wild ungulate. I've had some rodents like squirrels and nutria and so long as you let the meat chill for a couple days, tastes surprisingly good! But I've had wild boar, deer, moose, bear, and horse and they was some pretty rough experiences.
