Michael Jackson's hehe is one of his most recognisable vocal trademarks, a short, playful sound he used as an ad-lib in his singing and on stage. Fans and video editors have long isolated these tiny moments from his performances, turning them into reaction clips that travel across TikTok, YouTube and meme pages. The sound works because almost everyone recognises the voice instantly, even without any music around it. Today it survives mainly as a quick, cheeky reaction in short-form edits rather than as a musical excerpt.
