Similar to "The Shocker", "The Shiv" is a sexual act that involves forming a W with your hand like the Westside Gang sign. The dominant partner gives the more subtle female partner pleasure by inserting the middle and ring fingers into her vagina and the pinky finger of the same hand into her anus. This leaves the index finger free to manipulate her clitoris leading to maximal stimulation. She is pleasured by the slow/fast thrusting of the hand in and out of the orifices.
