The process of taking ones thumb and middle finger and pressing them extreamly hard on ones arm flab while yelling CRABBY CLAW! This usually results in extream pain to the person you are doing it too.

This requires two people. One people must take their thumb and index finger, and pinch that tricep of the other person's, without them suspecting it. This usually results in a lot of pain if done correctly, and a slap in the face.
