Skrrr grew out of hip-hop and trap music, where it is used as a vocal ad-lib that imitates the screech of tires during a fast turn or drift. The spelling varies online, with skrrt the most common alternative, and the short clip form spread through meme edits and short-form video, where a single screech could punctuate a joke, a drift, or a sudden change of direction. Because it is instantly recognisable and needs no lyrics, it has stayed useful as a quick transition sound long after its first wave of popularity.
