The line comes from Grease, where it is directed at Roger Putzie in a moment of exasperated disapproval that fits the show's mix of comedy and high school drama. Fans have lifted the short exchange from the musical and shared it as a standalone reaction sound, because the insult is instantly understandable even without knowing the plot. It survives online for the same reason many theatre lines do: it is brief, quotable, and perfectly timed for calling out behavior that viewers already recognise as wrong or over the top.
