The Boston crab is a professional wrestling hold that typically starts with one wrestler lying in a supine position on the mat, with the other wrestler standing and facing him. It is a type of spinal lock where the wrestler hooks each of the opponent’s legs in one of his arms, and then turns the opponent face-down, stepping over him in the process. The final position has the wrestler in a semi-sitting position and facing away from his opponent, with the opponent’s back and legs bent back toward his head.
