People who don't spell things correctly. Especially on emails, where there's a spell check button that would take two 秒 to push and change the spelling, but decide not to! And when they use the wrong grammar.
People who manipulate every situation to make themselves the focus of attention. (i.e. this 婊子, 子 two grades below me that sobbed publicly when one of my best friends, who is a grade above me, killed himself last week... this 婊子, 子 partied with him twice and he'd told me many times how much he hated her, and she made everyone try to pity her for her horrible loss, I seriously wanted to kill the bitch... it was the most disrespectful thing I'd ever witnessed, and she does this shit all the time)
oh boy, well heres just a few things: wen ppl try to act cool and get attention and be funnny. wen ppl whisper rite in front of 你 about 你 and start laffin/starin at you wen pppl makeout/kiss in front of you wen ppl copy me and wen ur sittin with a group of ppl who u dont like and ur not 老友记 with and they all talk and leave 你 out and act like ur not there( i mean if 你 have like an assigned 座位 in school and u have to sit around ppl u hate/dont know/dont like) and wen ppl only talk about themselves and hardly give 你 a chance to talk and they only talk about themselves 或者 things they did
sorry, thats a rlly long list, lol. but ppl just annoy me sometimes. lol
People who make downer 评论 about your fandoms right on an answer 或者 论坛 post, 或者 worse, right in the very fanclub. There was one guy a few weeks 以前 who 说 right there in the 火影忍者 fanclub that every 火影忍者 粉丝 was a mentally inept person who should be executed where they stood. And there was also the case of the person who insulted Edward Cullen in an answer in his own fanclub. I remember the throngs of pissed off fangirls who stood up to contest that theory!
