Going to a high school, I've got a lot of people who are pissing me off:

Goths
Cheerleaders
Jocks
Preps
Punks
and the Joe Schmoes

Nah, not all of those groups, though that's who the average high school student hates. I don't hate certain groups, over all, I am pissed of by supremacy. People who think they're above others with no reason to be.

Other than that, not too much pisses me off.
