Okay in the defense of peanut butter, plain smooth peanut butter is pretty meh. But crunchy peanut butter is pretty awesome especially the honey roasted variety. Anyway I don't have one particular food I dislike a lot, but I'm not really a big fan of seafood but not everyone likes it and there are plenty people that are allergic to certain kind of seafood. Also when it comes to seafood I never had lobster, crabs or any types of shells (oysters, scallops etc) and I really have no plans of ever eating any of those either.
