4Chan is, as many would say, the asshole of the internet.

Aside from this, 4Chan is also where every meme ever came from. Many of the things on 4Chan are horrible things (such as goatse). The very few gems that are actually funny make their way to other places on the internet.

This site is home to many Trolls, who use things like goatse and /That Series/ ("Of Warlords and Pleasures"), and other things that cannot be unseen to terrorize other sites through obscene spam. Most of these things are on /b/, which is basically the armory for Trolls. I recommend that, if you feel the urge to visit 4Chan, you leave any religious beliefs, morals and etcetera behind. Also, please make sure there is nothing nearby for you to kill yourself with, becaue you /will/ lose all hope.

Much like the Fight Club, you do not talk about 4Chan. Not ever.
Guy1: What's 4Chan?

Guy2: The asshole of the 'net.

Guy1: What?

Guy2: You really don't want to know, trust me.

Guy1: Yes, I do.

Guy2: Okay then... *brings up 4Chan on laptop*

Guy1: OhmyfuckingGodkillit! No, wait, kill me! There is no hope!

The birth place and the death bed of the internet. It where things are created and where things are destroyed. It is all powerful and knowing and for one to survive in its culture, they must leave behind all previous thoughts of normality. What's happens in 4chan, stays in 4chan, until posted anonymously elsewhere.
4chan is dangerous and omniscient website.

A site that has disgusting pictures, along with disgusting people. This site consists of blogging, and complaining. Low life scum more commonly use this site. While more sophisticated, and morally correct people use tumblr.
He's so gross, and morally corrupt, I bet he has a 4chan.
