SLP's mom: Everyone liked to joke about fucking or raping SumLittlePunk's mom. This would turn into a long running joke, i.e. "This thread sucks harder than SLP's mom!"
CCB the sheep fucker: Another long running joke about how CCB, a popular poster, liked to have "relations" with his pet sheep. This was especially prominent during the McMahon Hater Show days.
Twod: A euphemism used by Pegster in place of any slur. This caught on pretty quickly. "Look as these twods!!"
Winston: Another invention of Pegster. It was a gimmick account based on a UK television character.
Goatse: A photo of a man displaying his distended anus that many posters, most notably Pumpkin Escobar liked to post at certain times.
This is the picture. Warning! Not for the queasy!
1337 5p33k: A form of typing that was popular among some posters. Mostly done to mock others or to be sarcastic to other posters.
Powerbomber12345: A gimmick thought up by several veteran posters. PB was basically a mockery of every "n00b". He was representative of all the dumbest posters on WZ. It was not even an actual account until a poster named Big S took it upon himself to register the account name and post with the account, making all the rumors of PB copme true.
Police Cops!!!11: A show put on by pegster.
Winklegate: An infamous AOL group chat between a "hacker" and prominent members of WZ that is widely considered the funniest AOL chat ever.
