Pickled Pigs Feet
Any fish. Especially if they still have the head attached! They look too much like relatives that way.
Any fancy pantsy term for some kinda baked/broiled/fried animal genitality.
Green Peppers (love 'em, but they sure as hell don't love me)
Any food that smells like something that leaves the body, instead of going in it!
Things made of soy that shouldn't be.
Give your list kids!
