What else does Ruh-roh mean?

  • Hanna-Barbera cartoon of a Hanna-Barbera dog saying “Uh-oh”, beginning with THE JETSONS’ Astro 1962, and continuing on with Scooby-Doo during the Seventies. Astro spoke a type of English, except words that had beginning consonants were replaced by an “R”, and the “R” was used in front vowels. Scooby Doo had less fluency, but was still able to say “Ruh-roh”, which was a running gag for when things got bad. Sometimes, “Ruh-roh,” is used to joke about dogs. As an example of this, a story was recently published in which Air Canada accidentally freed a San Francisco Airport dog from its cage. Meaning rough: I goofed or I’m in trouble. “.
