an overrated and hyped-up website, 4chan mostly consists of a bunch of dorks (who are all anonymous since there are no registered usernames) posting boring pictures of anime and naked chicks.
after reading the top definition on urban dictionary, i thought i was going to be awestruck by 4chan. instead i discovered it to be lame and uninteresting.

A bunch of hackers, furries and loners (usually not by choice) who think they invented every internet meme there ever was.
See any meme, then look on /b/ Someone will take credit for it. Fuck 4Chan

Possibly the end of the internet, or source, or center, or beginning. Everything you can ever think of is found here, whether you want it to be or not. This website is slowly dominating pop culture and the world. Several rules are often followed when entering 4chan (they are the rules of the internet, unsurprisingly invented for, at, and by 4chan):

1. Do not talk about /b/.
2. DO NOT talk about /b/.
3. We are Anonymous.
34. There is porn of it, no exceptions.

These people are the society of the nobodies. They are the middle generation, born to go nowhere and do nothing with their lives. Their form of therapy? 4chan.
1 - "So my good friend told me about this website he goes to. It's called 4chan or something."
2 - "You poor soul."

Also known as the asshole of the internet. There is so much shit on this website, that if you continuously refresh your browser, you will see some random ass entry even stupider than the last. This site is divided up into approximately 485785786785476 sections, each with its own random abbreviation. For example the section titled "Random" is abbreviated as "/b/".......... why the fuck this is, we dont know.
4chan is the most ridiculously ridiculous site you will find out there. if your bored out of your skull and need a quick laugh, go to this site right fricken now.
A place where eunuchs congregate to curse at and insult each other. Basically a hangout for the mentally retarded and socially outcast.
Guy 1: I went to 4chan's random base and people were posting pics of guys sucking their own dicks.

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

Guy 3: No fuckin' shit.

2chan's American cousin. An image board where equally wonderful and horrible pictures are posted constantly. Stay out of /b/ until /g/ is restored.
For god, for country, 4chan.

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!
