The line comes from Man's Not Hot, the 2017 track by British comedian Michael Dapaah as his character Big Shaq. It first went viral after his freestyle on BBC Radio 1Xtra's Fire in the Booth, where the improvised gun sounds and deadpan delivery turned a parody of road rap into a global hit. Clips of the verse spread across YouTube, Vine-era edits and later TikTok, and the phrase became shorthand for comic exaggeration. It remains popular because the sound is instantly recognisable, easy to drop into edits, and still funny without any context.
