Anaconda Choke

From FightWiki

An anaconda choke is an arm triangle from the front headlock position. The man on top threads his arm under the opponents neck and through the armpit, and grasps his bicep. The performer then attempts to pin the bottom man onto the trapped shoulder so as to better interrupt the flow of blood, all the while applying pressure with the grasped bicep. He may accomplish this by rolling the man over the untrapped shoulder, (known as a gator roll) and use the momentum to turn the man onto his trapped shoulder.
