Kick

From the Super Mario Wiki

Kick is a move closely related to the Punch. It is either part of a attack combo or a midair attack. In Super Smash Bros. Melee the player can use it anytime. Almost every playable character with legs can use it, though Boo uses his tail instead.

Mario, Luigi, and Wario use it to end an attack combo in Super Mario 64 or Super Mario 64 DS. The move also appears in the Mario Party Series and Super Smash Bros. Melee.
