You will need two people, a car, and an unsuspecting victim. This is the act of having sexual intercouse with someone in the back seat of the car while your friend is in the trunk of the car. The friend in the trunk usually does stuff to interrupt the act such as moaning, controlling the music, or making noises. After the act is over, the friend gets of out the trunk and makes his presence known while also making the sexual partner sit in the back seat while you drive them home.
