A fighter will grab the opponent's foot and lift their leg off the ground. Then with one hand grab the opponent's toes or outside of foot, and with the other wrap around the ankle and through the "hole" created and grab his own wrist. Essentially putting the opponent's ankle in a Key Lock. Then they will bend the opponent's ankle.

A variation of this move is the grapevine ankle lock, in which the fighter applying the hold falls to the mat and scissors the leg of the opponent. This stops the opponent from rolling out of the move and makes it harder for him/her to crawl to the ropes but lessens the pressure that can be applied.
