The phrase comes from The Howard Stern Show, where producer Gary Dell'Abate earned the nickname Baba Booey after mispronouncing cartoon character Baba Looey in 1990. Stern and listeners repeated it until it became his permanent nickname and a show catchphrase. Fans began shouting it at golf tournaments, concerts and live news reports, turning it into one of radio's most recognisable prank calls. Online, the short shout survived as a soundboard staple, shared whenever a random, disruptive yell is funnier than a proper reaction.
