Not sure if this has been named, but this onloy works as Pit. When gliding, if you use you're glide attack or hit the ground ate right angle, you will slide a distance equivalent to wavedashin in Melee. During this "Wing Dash" as I call it, you can use any Smash or Special and get a boost in distance. It doesn't work very well with MetaKnight or at all with Charizard, and I call it Wing Dashing provided no one else has found this
