When you don't shave your grundle and ball sack for a couple months then do an activity so it is sweaty and smells like shit. Then you find a person repeatedly smack them in the face with your sack and rub your grundle all up on there face while getting a rusty trombone. When you are about to cum you turn and bust on there upper lip getting the pubes to become a facial mustache.
