Preppies - actually a two sided coin for me. I hate preppie males but like preppie rich bitches (mostly because I want to "take them down from their high horse" - as much as I hate to say it [and really, this shouldn't be too surprising], I kinda sorta want to...well, to put it bluntly, "do stuff" to them. Not that I actually would)
Teenagers - and people who say they hate teenagers (eyes Enlightenment, don't come to me when the nuke comes). My own kind can be damn annoying, but people who say they hate all teenagers across the board really fucking piss me off above anything else in the world. A teenager's life is much complicated in part by such people who have the arrogance to stereotype teenagers into one kind, and then discriminate against them and deny them opportunties because of such. Seriously, I put such an arrogant person into the hospital for that.
Trektards - obvious
DorkStar - Another person I want to put into the hospital.
Anybody who says they hate Mr. Bean/Black Adder - this oughtta make our Mr. Bean proud
Straha - just kidding
Arminiass - whoever doesn't get this seriously needs to visit here more often
stereotyping in general - the second thing that pisses me off the most
B-1B Bashers - ohhhh, they piss me off so much
Mike Wong Bashers - see above
Star Wars Bashers - see above
Anybody who gets on my fucking nerves - ohhh, do I ever wish killing was legal....

Snow Boarders (the only people Skiers think are too arrogant)
PTB's (Our socitey needs MASSIVE reform, and the Powers-That-Be simply need to DROP DEAD! I don't necessarily politicians or the like, what I really mean perhaps are the abstract ideals our society un-necessarily adheres to. This goes more for current legal issues than the above already mentioned)

Romulan_Nemesis, not because he's gay but because's he's teetering on becoming a flaming Trekkie
anti-gays
I'll think of more later
