4Chan 

The birthplace of memes, and where the Internet dumps their waste. Most people try to avoid it, due to the mental health issues involved.

4chan 

Where Chuck Norris forsook his wisdom. Where Monty Python denied their genius. Where the ancient Flame Warriors sealed the great evil Stupidity. This monster eventually escaped by its soul resides there still. It is a testament to the eventual downfall of Mankind. Only when the almighty Banstick awakens (And maybe if Microsoft takes over the internet) will it be slain. Should Rosie O' Donald ever be allowed to merge with 4chan, not even Chuck Norris can bring her down on his own.

Hell would have made 4chan a business if Rosie O' Donnell wasnt trying to claim the Twinky of Delicious Hate.

A message board on the Internet where anime fans from all the world over congregate to post pictures.

4chan is the coolest thing since 2chan.

Fark + anime = 4chan.

4chan is as funny and interesting as you'd expect a board full of anime porn would be.

4chan 

The evil twin of Reddit, on hallucinogenic steroids, narcotics and various other drugs.

Although evil might not be harsh enough. I don't think there is a harsh enough word for it.

Warning: contains explicit content illegal on most planets.

Don't go to 4chan. The dark web has surfaced.
