The Testicle Twist, Pull, and Squeeze Tactic:
Grab the attacker's testicles. If you can't determine where exactly his testicles are located either because it's dark or because he is wearing thick pants, grab in his general crotch area. Executing the technique on his **** will still be effective, although grabbing the testicles will bring him much more prolonged pain.
Once you have grabbed his testicles (or whatever you can get a hold of in his crotch area), twist them in a quick, concise motion. Twisting a full turn is not necessary and will be difficult for you to do. Instead, twist a half-turn or even a quarter-turn. The key here is a fast, powerful twist that will surprise him. If you are unable to twist for whatever reason, a squeeze will be just as sufficient.
After twisting, quickly pull what you're holding. Pull as if you are trying to pull his testicles out of his body--the harder you pull, the better. Your life is in danger and you are completely justified in causing him incredible pain. Show no mercy.
Follow these steps and you will have successfully executed the grab twist pull testicles self-defense technique. The entire process should last no longer than a couple of seconds and your efforts should immobolize your attacker. Beware of grabbing, twisting, or pulling for too long or the attacker may cause you even more harm in order to stop the pain. Remember: execute the technique quickly and escape while he is trying to recover.
