kick in the nuts

When a girl uses her leg to absolutely pulverize a guys most precious organs. Always results in the boy falling to the ground holding on for dear life to his poor broken balls and screaming for mercy.

John was being a dick so Amy gave him a hard kick in the nuts as hard as she could. He fell down screaming and holding his now broken balls to see if he could salvage any part of them. Needless to say he stopped complaining and never had any kids after that moment
