The phrase comes from Man's Not Hot by Big Shaq, the comic character played by Michael Dapaah, after his 2017 Fire in the Booth performance spread online. Its nonsense ad-libs, built around skrrra and similar mouth-made noises, were quoted, remixed and clipped far beyond the full song. The skrrr moment became a standalone reaction because it summarised the joke in seconds: exaggerated confidence in a completely deadpan voice. It is still used in short edits and memes whenever a person, car or character is meant to look fast, flashy or effortlessly cool.
