During vaginal sex from behind, i.e. doggie style, the man, or woman with strap on, inserts index and middle fingers into the anus of the pentrated. Forming the fingers into a hook shape, the woman is lifted up and down on the phallus by the "hook", or hand, as if she were a piece of "meat." Hence, New Jersey Meat Hook
I bent her over and gave her the new jersey meat hook. She loved it... absolutely loved it.
