A category of music, mostly bands from the 80's to early 00's, now considered revolutionary and created permanent ripples that influenced new music.
These bands were often called alternative, indie, folk or underground in their time. Their styles of music quickly became so popular it was absorbed into modern mainstream rock, pop, etc.
"Spotify says you really like permanent wave? It means you probably listen to a lot of David Bowie, Nirvana, Oasis and other influential bands that remain popular."
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.
