woop just saw this.
its a term referring to a type of hiphop that has been around for years, but has recently become a little bit more defined into a culture.
its basically hiphop that is steeped in the visual and audio essence of 90s low quality vhs type of things. stuff that was popular growing up in the late 80s early 90s. nintendo, sega, pokemon, anime, windows 95 apps. there is also heavy dependence on hallucinogenics, hydration, the ocean, space. very dreamy trippy stuff with a lo fi edge to it. i think these videos will describe it much better.
