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.

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.

Basically what Voldemort and Taliban would be as an Internet site, talking shit about 4Chan or even saying 4chan is forbidden on some forums because they're afraid that 4Chan members will pickup on it by Google search and wreck their sites. 4Chan is anonymous's stomping grounds and they're guys you don't want to fuck with, and they have the ability to ruin your life well pass the internet as they are quite skilled and cool hackers. They were even revving up to take on AT&T for a supposed site banning around late 2009.

Their latest thing has been the Jessi Slaughter fiasco, which everyone thought was going to be the end of 4Chan, but it wasn't. It also led to a war on Gawker.com that failed, not because the 4chan hackers suck, because Gawker got lucky and it was an unorganized raid on Gawker's servers, and some of Gawker's technicians caught it before it could go down.
"Hey man 4Chan is possibly responsible for making the internet a way cooler place. Not to mention most people use memes from their without even recognizing it.

The most random place on the internet. The plus side is there are no rules, you can vent away, and say and post the most fucked up things you want, and it's completely anonymous, there aren't even proper usernames. The downside to that is you will see some pretty fucked up shit. But you will also see lots of funny shit, and you can go on the particular area of the sites that suit your interests. Imagine reddit but more anonymous, and with more freedom of speech.
Guy1: Hey did you see this meme on instagram?
Guy2: No I saw it 2 years ago on 4chan, however the version I saw was significantly more graphic.

From my own experience, 4Chan is literaly the 2b2t of the internet. Right when I entered it, BAM porn ad, then guess what ? There were 4 nsfw post in the front page !!! This site is a place for people who wants to make trash.
Person 1 : Yo man I went on 4Chan and there is a lot of crappy stuff
(disrespectful/sexual pictures)

Person 2 : Why ? You know what people from Urban Dictionary wrote about this.

Person 1 : Yeah but you know I'm curious, but at least I can confirm what they said.

4Chan is trash, don't go here, unless you're a wild person

A Japanophile image board. Japanophiles from all fifty states who share opinions on why Japan is superior to every other place in the universe, post Japanese tentacle rape pics (without getting in trouble from their parents; it's all completely anonymous), and share unfunny inside jokes such as "O RLY?".
Japanophile: hay man hav u sene da l8est naruto
