The testicle method is a method of self-defense created by martial arts expert John Perkins. It is a simple yet effective system that uses the body’s most vulnerable parts, such as the testicles, to protect against an attacker. The technique involves striking an attacker’s testicles with the palm of the hand, knee, elbow, or other body part. This will cause immense pain, disorientation, and can even knock the person unconscious. The testicle method is a great way to defend yourself in a threatening situation. It is quick and efficient, and can be employed with minimal effort.
