Wavedash

A wavedash is a technique/physics engine exploit in Super Smash Bros. Melee that is performed by air dodging diagonally into the ground, causing the character to slide a short distance. While it is uncommon in casual play, high-level play of Melee effectively requires proper use of the technique; the Melee community sees wavedashing as an advanced technique superior to dashing because it allows players to perform any ground action while moving horizontally on the ground.
