-Noob threads.
-Posts that are fifty lines long and only contain one paragraph.
-Sloppy internet writing. It really isn't that hard to capitalize properly, spell, and use correct grammer. It makes it a lot easier on the other members in the forum to read with nice writing.
-People who drink so much they throw up, and then are totally against smoking marijuana. Hypocrites!
-Loud Heavy Metal Music.
-People who are obsessed with material possessions.
-Guys who feel as though they have to prove their heterosexuality by making non stop sexist comments whenever they see an attractive girl.
