Baba Booey began on The Howard Stern Show as a nickname for producer Gary Dell'Abate, after he mispronounced cartoon character Baba Looey while discussing animation art in 1990. Stern and the cast repeated it until it became his permanent nickname and a wider catchphrase. Fans and prank callers began shouting it to end calls, and television cameras later picked it up at sporting events, news reports and public appearances. That long life as an in-joke explains why a single shouted phrase still works as an instant punchline online today.
