A combination of a Wormy, (which is where one puts their finger in someones butthole) followed by a Jimmy Tap
The Wormy causes the victim to thrust forward into the Jimmy Tap causing excruciating pain in not only the butthole but the balls and penis as well. These are usually exchanged as practical jokes or pranks between friends.
