The Hot Dog Roll is a great way or reversing your opponent from your back, especially when they are about to break free from your guard. It requires that you already have a Kimura in place, and have his shoulder clamped down tight. Then the rest is about moving in the opposite direction that your instincts would tell you to.
This move was named by one of my brother’s Kimura Trap students, Keenan Cornelius, who had great success in his career utilizing the Kimura Trap System.
