gogoplata
A gogoplata is a type of chokehold also called Kagato-Jime in Judo, that is used in grappling and was popularised by practitioners of Brazilian Jiu-Jitsu.
The gogoplata is executed from a guard, commonly from a "rubber guard", where the legs are held very high against the opponent's upper back. The fighter then slips one foot in front of the opponent's head and under his chin, locks his hands behind the opponent's head, and chokes the opponent by pressing his shin or instep against the opponent's trachea. A variation called a Locoplata (popularized by Eddie Bravo) is when the practitioner uses his free foot to push up on the choking foot and increase pressure on the trachea.
Former WWE professional wrestler The Undertaker began using a variation of the move in January 2008 on SmackDown!, which would cause opponents to spit blood from their mouths. Former SmackDown! General Manager Vickie Guerrero (who was in the position at that time) would later kayfabe ban the move for the protection of the other wrestlers and strip The Undertaker of the World Heavyweight Championship as punishment for its use, an unprecedented move.
The move, now called the Hell's Gate, has since become one of The Undertaker's finishing moves.
