The Anaconda choke is an arm-triangle or head-and-arm choke in Brazilian Jiu-Jitsu where you are facing your opponent's back, but with their legs point away (as when you are sprawled on the opponent's back), unlike with the position of a rear naked choke, and also relying on the opponent's own trapped arm to pressure one of their carotid arteries. It resembles the similar D'Arce choke, but with the figure-four arm lock happening near your opponent's armpit, rather than near the opponent's neck.
