The sound comes from Young M.A, the Brooklyn rapper whose 2016 breakout single OOOUUU turned its hook into a cultural catchphrase. The track spread through clubs, radio and social media, and short clips of its swaggering vocal were soon reused in memes, reaction videos and edits. Its simple, instantly recognisable sound made it easy to drop into almost any funny or dramatic moment, and that flexibility has kept it circulating on TikTok and short-form video long after the song first charted.
