In Super Smash Bros. Melee, characters who's walk-acceleration is lower than their traction value after wavelanding backwards can buffer a slight walk forwards to decrease the momentum lost. The walk input must be at its lowest value to perfectly execute the tech. (rough translation of inputs) Characters with low traction (Luigi) benefit worse than those with higher traction values in Melee. (i.e Gannondorf can benefit from the Koopa Backdash Wave Slide Hover Walk Moon Landing more than Luigi in terms of distance)
Youtube has more info on this.
The Koopa-Backdash-Wave-Slide-Hover-Walk-Moon-Landing can make virtually anyone feel like they are playing on ice.
While fucking a girl, bent over the bed, you pull out, run to the opposite wall, tag it, then run back as fast as you can. Attempt to reinsert your cock into the girl while at a full sprint. After that is acomplished, lean forward to allow your cock to fall out and slade across her back, plant your hand on the bed, then vault your body into a backhand spring, land on your feet and yell shazam!
"Wow i cant believe i pulled off a Running backhand slip n' slide!"
