The clip comes from Michael Jackson, whose high pitched exclamations and ad libs became one of the most recognisable parts of his singing style during his solo career. This wooow is tagged to Don't Stop 'Til You Get Enough, his 1979 disco hit from Off the Wall. Short Jackson vocal hits circulated widely on soundboards and in fan edits because they are instantly identifiable from just a fraction of a second. This one survives as a quick reaction sound, reused whenever creators need unmistakable pop star excitement without playing a full song.
