Spleef 

A competitive sport in a 3D sandbox indie game called Minecraft. Gameplay consists of removing floor blocks from a stadium to make other players fall through the floor. The last player standing is declared the winner. After the game the floor is filled back in and the players compete again. Spleef is played in a specialized "Spleef Arena" composed of the main Spleef floor, a viewing area, and a lower floor to catch losers. The name is a pun on the word Grief, as the players resemble Griefers trying to make the other players fall through a floor.

Oh man, that last round of Spleef was intense!
