A professional wrestling submission hold also known as Sharpshooter elsewhere.
This hold begins with the opponent supine on the mat with the applying wrestler stepping between the opponent's legs with his/her left leg and wraps the opponent's legs at shin level around that leg. If the applier decides to cross the opponent's legs around his right leg, he has to cross the opponent's right leg over their left, or, otherwise, he has to cross his opponent's left leg over their right. Holding the opponent's legs in place, the wrestler then grabs the opponent's leg which he has crossed over the other and steps over him, flipping him over into a prone position before leaning back to compress his lower back.
Its original name is Sasori-gatame (Japanese for "Scorpion Hold") and is invented by Choushuu Riki. Sting then popularized it in the United States under the name Scorpion Deathlock and later on, Bret Hart adopted it under the name Sharpshooter.
