A self-righteous punk who spends his life making insulting remarks about the United States on internet message boards and threads without actually saying anything substantial - or backing up their criticisms with facts - because bitching about the US is the "cool" thing to do.
Will often express a desire for all Americans to die, support for jihadists and/or jihad, that the US looses in Iraq, that 9-11 was a great thing, that all Americans are fat, that all Americans are "rednecks", that all Americans are stupid, etc.
A-hater: DOOD AMERIKA SUCKS!!!! U GUYS FUCK EVERYTHING UP!!1!! JIHAD FOR EVAA!!!1!!1!
American dude: Yeah, piss-off you fucking a-hater.
