To painfully hit someone in the balls by the flick of the wrist and laugh on their behalf or roll on the ground if it is done to you.
I had 3 friend who were spending the night for 2 weeks while my parents were gone. They gave me a wedgie and pulled my boxers over my head. Every time I tried to pick it out they would hold me down and would each ball tap me 100 times. (I never got the wedgie out for the entire two weeks and I counted I was ball taped a total of 15,900 times).
