A theoretical storage device that a man tries to keep his cock in while out in a public place, intoxicated, and surrounded by pieces of ass. The device is located in a man's mind and keeps him from cheating on his girlfriend and avoiding guilt. The device usually always fails.(special thanks to Bobby C)
Cal tried as hard as he could to keep his cock in it's dong holster but he gave up after he met the 19-year old nursing student who wanted him to fuck her fartbox.
