The act of taking a pillow and crawling between the box-spring and mattress of a twin-size bed. (Full, king, and queen mattresses are too heavy.) Lying on your back, positioning the pillow between you and the mattress, and thrusting your hips against the pillow. Beware — If someone walks in on you, you'll have a tough time talking your way out of this one!
