The phrase comes from The Howard Stern Show, where longtime producer Gary Dell'Abate became known to listeners as Baba Booey. Fans adopted the name as a running joke and began shouting it during live television news reports, golf tournaments, and other on-location broadcasts, hoping to be heard in the background. The prank spread because it was simple, harmless, and instantly recognisable to other listeners. Decades later it remains a shorthand for crashing a serious broadcast with a playful, insider shout.
