Michael Jackson built his singing style around sharp vocal tics, from the hiccup and the 'hee-hee' to short shouted greetings that became as recognisable as his melodies. Fans have clipped those moments for years on soundboards and in fan edits, isolating a friendly 'hi hi' because it works without any backing track or context. The clip spread as a lightweight reaction and entrance sound, especially in meme videos where a familiar voice can set a cheerful tone in under two seconds and signal an impression is coming.
