A child's game played on a trampoline. It consist of 3+ individuals who bounce ferociously on the trampoline trying to knock each other down without making physical contact. The first to fall is beat down or kicked and punched until he/she gets back up and the game continues. If two or more fall they can be subject to a beat down as well.

The game originated in 1998-1999 at a place called "The Manor" in Hemstead, Long Island, NY.
