In this game, the idea is to place a color(s) in front of the word listed by the previous poster. For instace, I might offer the word "cow". The next poster would then choose a color for the cow, such as "black and white cow". Then they would come up with a word for the next poster to color. The game can get as crazy as you want it to be.
I might say britney spears. The next poster might respond "fecal brown britney spears".
