(Non Sexual)
A play on the dynamics of a typical backyard trampoline (and possibly others), requiring two people... one person jumping, the other person standing near the outer springs, ready to initiate the double
bounce at the appropriate moment.
At a certain point in the
air (timing is crucial, but relative to the individuals taking part), the person standing off to the side stomps down near the landing area of the trampoline just as the jumper comes in.
The initial
stomp and following landing result in more
force being applied downward than the jumper is able to initiate on his/her own. When successful, the jumper
will be propelled significantly higher than usual.
