In mixed martial arts and submission grappling, it is sometimes referred to as the Twister and has been taught extensively by Eddie Bravo in his 10th planet jiu-jitsu system.
[1] It is not to be confused with the guillotine choke, a move from the front headlock position that is used in submission grappling.
From the top, the same side leg must hook opponent's inside thigh, gripping the ankle with the attacker's foot.
Next the attacker reaches across to grab the arm opposite to the side that the leg ride is on.
This final position is the guillotine, and the attacker applies it by squeezing as softly as possible (to avoid spinal injury) while maintaining the leg hook to prevent the opponent from escaping.
