no anime has ever made me throw up, but mao-chan DID rot my teeth with its sugaryness (it rocks nonetheless, akamatsu kicks the ass)
what does make me want to toss me cookies is the yu-gi-oh card game. have you ever sat and just listened to the idiots who play that? i thought the object of cards was to surprise your opponent, not constantly talk about how youre about to rape his mom in the ass and scream booyah while showing your hand to one of your idiot friends.
i know that was making HUGE generalizations, but i was talking...generally. my girlfriend plays yu-gi-oh and she does none of that...she does it more out of boredom...
EXCEPT the dark witch card. anyone seen this? its hilarious. look at her expression and her position...genious.
