A game played by at least two ass ninjas where you get in a circle and jerk off on a cookie. The last one to finish has to eat the cookie. Commonly recommended when there isn't shit going on and you and your buddies can't find anything to do. Although I don't know anyone who has actually ever played it, thank god.
Joe: "Hey what the fuck are we doing tonight?"
John: "I don't know, let's play cookie."
Jeff: "Fuck that man, your gay."
