York Peppermint Patties. Actually, anything chocolate mint. I don't care what anyone says, chocolate and mint do not go together.

Anything with real coconut. I love coconut flavor, but I can't stand the texture of the real thing. I bit into a Mounds once as a kid, not knowing what was inside, and it tasted like regret. T_T

Wax candies. Wax teeth, wax coke bottles, etc. Wax isn't candy, it's candles! (And yeah, you're not supposed to eat the wax, but you still put it in your mouth and it tastes disgusting.)
