Geez, there's almost too many to name, but here goes,
Peeves:
Reality Shows - bullshit networks decide its easier and cheaper for people to make their own shows. What makes it even worse is the feeble attmepts to draw in stupid viewers, by telling them that this time theres a twist you didn't see coming, and its going to be better than ever.
Changing your status to "away" on MSN - If you're away, then just fucking sign out. You're not there, no one can talk to you, or you're just pretending to be away so you don't have to talk to people you don't like.
Asian animation students - the program at my college is specifically designed for traditional drawn animation, focussing on western styles like Diseny/Pixar. To enter the program, a portfolio is required to show what you know, and the outline clearly says, "no comic book art/anime, or images of the horrific..blah blah..etc" The vast majority of asian applicants still draw everything in an anime style, get rejected, and then claim they were discriminated against, and even some go as far as to file complaints alleging racism.
People who try to get me to drink - I don't drink. I'm 19, I've never had an alcoholic drink. I see no reason to drink, i have a good time with friends no matter what I'm drinking, it could be pepsi, it couild be orange juice. Still, everyone looks at me like I'm a fucking alien when I tell them I don't drink. I tell them I have no reason to drink. I'm not depressed, I'm not stressed out, my life is fine. Still, everyone tries to get me to drink at every opportunity, to the point where even my parents have questioned it. Fuck alcohol, Pepsi is good.
People who have no idea waht they're favourite songs are about, or just generally don't care, because its a popular song and its cool to like it - I've encountered far too many people who claim to like a certain genre/artist/song, and when I ask why they like them, the answer is usually something like, "they're cool," or "its catchy." Fuck that. They have no idea what the songs are about, or in some cases, what the lyrics are. Then if you tell them, and they realize its stupid, they still try to rationalize it.
People who don't take the stickers off their hats - not a racial thing, but we all certainly can see who does this more than others, but its ridiculously stupid and to mention it to someone who does it is "disrespect."
And just a few quick ones:
People who believe the Bible was written by God.
People who don't believe in evolution.
NBA playoffs when 80% of the games are blowouts and people still claim that thay are "teh best playoffs ever!"
NBA Finals that have excessive foul calls.
Game series that barely update anything, and then advertise that something has been "completely redone" or allows you "more control than ever."
People/rappers who hate cops because they're trying to arrest them, even if they've committed numerous crimes. (see Tupac)
People who think AFI sounds like alexisonfire
People who haven't heard of Mitch Hedberg.
