This involves first waiting until
the victims back is turned. You must then pull down your trousers and underwear, completely exposing your
cock and balls. You then wait for the victim to turn around, and perfectly time a vertical jump, to ensure that you are completely airborne when their eyes first meet your tackle. The jump has a sort of 'zero gravity' effect on the male genitals, causing them to float up from their normal position, thus creating a new, unexpected and
interesting way of pranking your victim.
