Soreballs
(N) A gesture used to greet a friend and simultaneously rob him off his dignity. To give "soreballs", you extend your hand for either a handshake or high-five, and at the last second close your hand into a fist and swing into the testicles of your target with enough force to cause them to double-over in pain, but not cause any lasting damage.
When you see a friend talking to a good looking girl, a soreballs is a great way to acknowledge him and also let him know that he's not as cool as he thinks he is.
