actually its not a 4chan game, or, it didn't start on 4chan. its a game played on allot of different forums and image boards, its just associated with 4chan and all those other chans because, well its probably where allot of people first learn that game.
by the way I've never been to 4chan or any of those #chans. it's not like playing a game associated with them is going to degenerate every one and turn them all into trolls.
alos, this should remind you all of some one.
