A site where pretty much anybody can post anything.
I knew 4chan was not for me when I saw a picture of two teenage boys having sex. Jesus christ.
Tom: Hey, I was at 4chan yesterday and I saw some guy raping a goat.

Bob: Yeah, that sure sounds like 4chan.org to me

The worst invention in the world, bro. It's a totally oldschool website for noobs, nerds, and geeks of the internet. Don't get me wrong, there are totally radd noobs, nerds, and geeks, but users of 4Chan are totally not a part of that group.
Have you ever heard of 4Chan?

Yeah, and you must use it 'cause you're lame.

“ Outside the ordered Internet is that retarded blight of racist austism which lies and blasphemes at the center of all memedom—the boundless retard sultan 4chan, whose name no sane lips dare speak aloud, and who gnaws hungrily in inconceivable, unlighted forums beyond the internet and the real world, amidst the sad, pathetic penis's of vile twelve year olds and the disturbed monotonous whine of accursed fags. „
