When a man grabs his balls and pretends that he is playing craps. In other words, it is the art of whacking off with your balls in your hands at the same time that you are stroking your one-eyed monster.
Travis was at home enjoying his lazy saturday afternoon. Tommy decided to visit Travis and watch a GGW video (with a pillow covering his lap no less). Tommy went to the bathroom and decided to play some one man craps. Travis had to use the batroom and knocked on the door. Tommy, obviously frightened, shreaked and blew his load shouting "Ahhhh, snake eyes!!!".
