i think the last meat you have left to taste is human meat
I legit would eat human meat if I had a proper opportunity to try some.
Like, I obviously wouldn't make it a staple of my diet, or hunt people down for it, but if offered in a location where I'm sure I won't get HIV or whatever, or arrested, then I'd try it.
I would like to try more 'exotic' meats too. Unfortunately I don't really like seafood much (or at least, not what I have had), and I'd be kind deterred from eating insects and other creepy-crawlies.
That mostly just leaves birds, mammals, reptiles and I suppose some amphibians.
The most exotic thing I've eaten was Alpaca. It was really nice. Surprisingly similar to beef, I found. But I think it's also got a little bit of a lamb-like flavour.
