The joke relies on Scooby Doo, the Great Dane from the Hanna Barbera cartoon franchise that began in 1969, whose wide eyes and goofy expressions are instantly recognisable. The exact recording of this shouted line circulated online as a standalone roast sound, separate from any official cartoon episode. It spread through short form edits and reaction videos where creators pair the audio with photos or freeze frames. Its popularity comes from the unexpected comparison, turning a familiar childhood character into a quick, light hearted insult that audiences understand immediately.
