The 'woohoo' style vocal wail is one of Michael Jackson's most imitated trademarks, a spontaneous-sounding ad-lib he threaded through live performances and recordings at the height of his fame. Short isolated clips of these vocal bursts began circulating on meme pages and soundboard sites as reaction sounds, prized for how instantly recognisable they are. Today the wail shows up in sports edits, gaming montages and comedy memes, usually as a one-shot burst of hype that needs no context to land.
