The Comics & Cartoons board over at 4chan.

Regulars of the board are called /co/mrades.

Often at war with /v/ (Video games) but I don't partake in those.

Better than the shithole they call /b/ will ever be.

I'm a /co/mrade AND DAMN PROUD OF IT

The Comics and Cartoons board on 4chan that consists of:

* Grown men idolizing comic book superheroes.
* Fanboys of 80's - early 00's cartoons that consider them to be the greatest cartoons ever made because they grew up with them.
* General threads of Adventure Time, The Regular Show, My Little Pony,, and Homestuck (the en vogue series as of May 2011) that spam the board.
* Trolls that post fetish artwork from deviantart and get 200+ replies.

Typical /co/ conversation

Digital O-Face. A replacement for the smiley face when sexting, generally used after a steamy hot sexual innuendo. It can also be used in stealth form by those with dirty minds during general text conversation, when an accidental innuendo is encountered.
