Rear Naked Choke
The Rear Naked Choke is a chokehold in martial arts applied from an opponent's back. Depending on the context, the term may refer to one of two variations of the technique, either arm can be used to apply the choke in both cases.
The choke has two variations: in one version, the attacker's arm encircles the opponent's neck and then grabs his own biceps on the other arm (see below for details); in the second version, the attacker clasps his hands together instead after encircling the opponent's neck.
Known as La Caina or Mataleon in lucha.
Sleeper Hold
The Sleeper Hold looks functionally identical to a Rear Naked Choke, which belies an important difference. Whilst a Rear Naked Choke applies pressure to the airwaves directly at the front of the neck to block oxygen from entering the body, the Sleeper Hold - devised during a time when tracheal chokes were illegal in wrestling - scissors the arteries at the sides of the neck close with the attacker's forearm & bicep, achieving the same result by blocking oxygenated blood's route to the brain.
A Bulldog Choke is a variant transitioned into from a regular headlock, which nestles the opponent's throat into the crux of the elbow from side-on. Thus allowing for the attacker to lean their full body weight back against the neck. Its best-known user is Jon Moxley.
