Michael Jackson developed his vocal hiccups and 'hee hee' ad-libs during his solo career in the late 1970s and 1980s, with the sounds becoming trademarks on albums like Off the Wall, Thriller and Bad. The clipped falsetto break appeared in songs, live performances and music videos, so listeners identified it with Jackson even outside a full track. As short-form video and meme editing grew, creators isolated the vocal as a standalone reaction sound, cutting it tight for remixes, parody entrances and dance edits where an instant Jackson reference is needed.
