Rear Naked Choke

The Rear naked choke (RNC) 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 term rear naked choke likely originated from the technique in Jujutsu and Judo known as the "Hadaka Jime", or "Naked Strangle." The word "naked" in this context suggests that, unlike other strangulation techniques found in Jujutsu/Judo, this hold does not require the use of a keikogi ("gi") or training uniform.

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.
