I can not stand it when an atheist is either an atheist for a stupid reason, such as just trying to rebel from their parents, or when an atheist is really defensive about not being religious. Such as when a teacher said something about Christianity to a class with only one atheist in it, and the atheist has to point out, "I'm not a Christian, I'm Atheist!" just because he likes to be different.
Also, I can not stand when people use chat speak in real life. Seriously? "WTF" has more syllables than what it abbreviates! Why must you say, "LOL," when if you think it's fun you'd be laughing?
I also hate it when people lose the game. I really did like the game a year and a half ago, when I was the only one I knew who played it outside of summer camp. Now, because every single person in my school plays it, there's probably someone losing the game every 20 seconds or something ridiculous. It's not nearly annoying as "No! I WIN the game! Take that!" No, you didn't win the game. I don't care if you stop playing or something, but you really didn't win the game.
I can't forget about "Your Mom" jokes. That's is pretty much the lowest form of comedy. How can you tell. No one laughs at your mom jokes. Seriously, no one really does, except maybe exceptionally stupid people. I have been known to freak out and yell at people when they say a your mom joke. And I'm not talking about "Yo mama's so fat..." type of jokes. Those can be funny in a cheesy, stupid way. I'm talking about "Do you remember what the homework was?" "Yeah, it was your mom." No, it really wasn't.
And of course, the thing that annoys me the most is when people say "gay." Why? Because ninety-eight percent of its usage is something along the lines of "My chair broke! This is so gay!" Is it? Is your chair really a homosexual? I really don't think it is! I don't think it's very merry either, you just freaking broke it!
The sad thing here is that this is less than half of what I could say, but I'm just tired of typing at this point.
