A sexual act that requires a flash light, and preferably a dark room or a camp fire. While banging a smoking hot female from behind, double penetrate her with the battery end of the flash light so when you turn it on, the flash light shines up under your face like you are telling a scary story. When she turns around, she will surely get frightened, tighten up, and/or scream. Perfect execution of this move will leave her with Goosebumps.
(Make sure to hold onto the flash light during the R. L. Stine when she turns around. if she gets freaked out and stands up and runs away, the light will be shining all over the place and you wont be able to see anything)
