It is one of the most common moves in a catfight, though not one that is often sought out or planned. A deadly combination of leg scissor and sleeper hold. Applied haphazardly at first, more to stop an opponent from getting away and turning to face than anything else.
But as thighs tighten and pull back, forearm slides beneath chin, and then efforts of a struggling opponent turn from offense to defense, to desperation, the move of opportunity becomes one of finality. Leaving she who applies the hold to lean back, hold on, and enjoy the feeling of her rival slowly weakening in her grasp. Until she can fight no more; instead finding herself helpless to resist whatever punishment may come.
