A game played with a doobie with many variations - the most common being where each person takes 3 tokes without exhaling and passes it on, then takes 2 tokes when the joint next reaches them (without exhaling), and then takes 1 (often large) toke before exhaling.
guy 1: dude... traffic lights?
guy 2: sure. pass the doobie.
guy 3: blaaaargh.
