A shitty forum that has become wildly popular. It is full of child porn images and the origin of many of the shitty internet memes that seem to be oh so popular these days.
Person 1: Hey, did you see that picture of the naked 12 year old having sex with a rhino on 4chan yesterday?
Person 2: Oh yes, I did. She accidentally the whole thing!

A message board and image board on the Internet where people congregate to post various kinds of pictures, flash animations, and discuss things such as anime. It is the English version of the original Japanese board with a similar system: 2chan.

The system that 4chan uses is Anonymous, so one can safely post one's opinion without worrying. One can use a name and a tripcode (a # followed by a 'password') to gain 'status' on 4chan.
Did you see that insane Flash movie on 4chan?

This is where the trash of the internet come out to play. What they post is exceedingly derogatory and immature. Most people, the completely sane minds, would not stray too far into it.
4Chaners should not have their own website to expoloit what they do.

A place where eunuchs congregate to curse at and insult each other. Basically a hangout for the mentally retarded and socially outcast.

Guy 2: That's fuckin' faggotry shit, yo.

Guy 3: No fuckin' shit.
