-People who type "ppl" instead of "people" and other of those little internet abbreviations. (but I find “ppl” most annoying).

-Mean people

-Sad people that always complain about how sad they are all the time and are always in a bad mood and have a stupid pessimistic outlook on everything, and people who're depressed that have to drag everyone else around them into being depressed and sad.

-Attention whores

-People who go "................................" or "!!" Punctuation abusers. :rolleyes2

-Being bored

-Final Fantasy VII

Yeah, I know that's not all, but that's all I can think of right now.
