What you call anyone who says or does something just dumb enough not to be punched in the face with a Buick.
Jimmy just told that hot chick he likes Dungeons and Dragons and eats a lot of ham while wearing a glittery cape. Jimmy's a freakin' crack monkey, dude. That's what happens when your mom snorts crack rocks and coffee beans and then goes to the zoo to have unprotected sex with mysterious, hairy blurrs. They held her afterwards and brought her flowers the next day. So I guess it was kind of nice, in an anti-Darwin sort of way.
