My uncle told me a story about my mums brother who was getting bullied in school. One day my uncle told him a judo move to use against side kicks. Another day he was being bullied and one of them threw a kick at him and all he had to do was step to the side and knee him in a certain part of the muscle in his leg and he did that and he was left on the ground screaming in pain as he gave him a dead leg witch basically stunned his leg.
