UFC featherweight Chan Sung Jung's historic usage of the devastating and impossibly painful twister is one of the most fondly recalled modern memories in the sport. So complex and progressive is the move that it is rarely seen in the division, but when the submission is engaged, you'll never forget what you've seen. An attack controlled from the back, the move cranks on the neck while twisting the body in the opposite direction, quickly putting pressure on the spine. The twister is a spine lock. Yes, you read that correctly. One of the most important bones in our body, essential for just about everything, is placed under severe pain and pressure by the move. When "The Korean Zombie" first locked it in, the UFC community was stunned. Mainly due to the submission being an accepted attack inside the Octagon. In a sport in which 12-6 elbow drops are a huge taboo, it seems crazy that it is okay to potentially place an athlete in a position where they could become permanently disabled. This being said, the twister is not a regular occurrence, much to the fighters' relief.
