A submission move from Brazilian Jiu-Jitsu sometimes used in MMA
style fighting. For this move you must be facing towards and be above the victim, who generally must be on the ground. One arm goes around the neck, the other under the opposite armpit, then they are locked and pulled in towards you. Next, put the first leg over the victims back, desirably the leg corresponding to whichever arm is around the victims neck. Then, throw the other leg over. To complete this move crank back with your torso, and the straightening action of your body applies considerable pressure to the victims neck.
I was going to put that guy in a Guillotine choke, but that's what he was expecting, so i sank the Peruvian Necktie in instead.
