The cattle catch (also referred to as reverse crucifix, iron cross or stocks) is a hyperflexing neck crank involving trapping the opponent's hands and forcing the head towards his or her chest.

By using the pinned arms and legs as a point of leverage, the combatant can forcefully crank the head towards the opponent's chest.

The twister is often confused with the spine crank since it involves a degree of lateral non-cervical spinal flexion.

It is performed from a back mount single vine ride position, where the top combatant has one "hook" threaded through the bottom opponent's legs and secured behind the ankle.

This was the first and only twister finish in UFC history until Bryce Mitchell defeated Matt Sayles with the maneuver in December 2019.
