art of doing this foul move, involves the
predator eyeing up his victim who is sleeping, then makes his move,only in stealth, one wrong move cud cost him his life, he observes his victim and waits to make the kill,
patience is of the essence here,a good fisherman knows wen to go in for the kill, the victim opens his mouth in the sleep and the predator is in there like a shot, pants down...arse on his face wiv his balls...phwoar the adrenaline
