A sexual act that requires a man and a woman. The woman lays flat on the bed where as the man stands up, grabs the woman's ankles, and then assumes the scissor position. He lifts up her ankles, and inserts his penis into her vagina. After the insertion, shake the woman violently while she is hanging upside down and imitate the sound of a Jackhammer.
That Tyler sure will give your bitch the ol' Jackhammer Jones!
