A move executed by a female during sex to prevent full penetration because the male's cock is too big. The move is executed in almost any sexual position, by the female bringing her arms up, putting her hands on the males waist or thighs and pushing away with her fingers, resulting in the cock reversing its penetration and also preventing any further full thrusts by the male to achieve maximum depth.
