The Boston crab is a professional wrestling hold that typically starts with the opponent lying supine on the mat, with the wrestler standing and facing them. 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 face. This often sees the attacking wrestler perform double leg takedown.
