A move that has had as much impact on the Mario franchise as moves such as the Wall Jump and Spin Jump. This move is usually executed by crouching in mid-air, but is sometimes performed by pressing the jump button twice instead (usually in Mario Party minigames). When used, the character will smash their butt on the ground, which can have many results.
This move can break or activate blocks from above, in contrast to the effect of a normal jump. It is sometimes the only way to defeat an enemy or complete a mission, such as destroying Chain Chomps' stakes in the New Super Mario Bros. series, and is usually more powerful than a normal stomp.
