A meeting place and breeding site for the utter dregs of humanity. A festering polyp in the dieing colon of society.

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.

4chan is the nexus of the internet, where everything goes to live and die. Especially famous for begetting the rickroll, SHOOP DA WOOP, and lolcats.

The most famous board is certainly /b/, the random board. After that probably comes /a/, the anime board, and then maybe /v/, the video games board.

...See Encyclopedia Dramatica for where much of 4chan goes to die.
I went on 4chan yesterday, I'm pretty sure that my brain fell out.

4chan is hell. The congregation of all assholes, pedophiles, creeps, hackers, and others on the internet. Memes spout from it, and spread quickly. 4chan is like a gigantic titan that should be either killed or locked away in Oblivion.
