The sphincter of the internet.
Where integrity goes to die.

yay.

A place where an overweight middle aged cyber virgin would go to post anime porn and talk like Terri Schiavo. This place is anonymous, because much like emo kids, no one here has any originality and they just post and repost something they googled and come up with some witty comment about it in the hopes of failing horribly and not being made fun of like they would in any other situation, like real life.
People make fun of me in real life and on 4chan, but atleast they dont know who I am on 4chan lololololoollololololololol

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 shitty site for closet homosexuals with no social life with nothing else than anime, gay porn, spam, retarded threads like "rate my (micro)cock", "need advice about <whatever>", "I hate jews and <whatever>".
Whoever wrote the first definition must have been on crack.
4chan sucks like hell but at least it keeps asshole trolls busy.

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.

the complete shit hole of the internet. its user consists of almost nothing but perverts and douche bags who act like assholes because since its anonymous and its over the internet they can act tough to make up for their insecurity's in real life.
oh look another post on 4chan about a 27 year old guy fucking a 16 year old girl and oh look... every comment is telling him to do it and post pictures of them fucking after ward's for them to see... i don't even know why i come here.

The origin of almost any fucking internet meme you can think of. Site is filled with taboo porn, stupid pictures and other stupid shit.

A couple of examples include the Rick Roll and the motivational pictures. This site has gotten pretty old, and should die immediately because everything they put out is no longer funny, amirite?
4Chan is the source of all the stupid memes you see these days.
