Red Robin is an American casual-dining chain built around gourmet burgers, and its sing-along YUMMM tagline comes from the company's television and radio advertising. The short jingle was designed to be instantly repeatable, which helped it move beyond commercials into internet culture. On soundboards and short-form video it is now used as a generic tasty-food sting, even by people who have never eaten there. Its staying power comes from that simple, happy delivery that everyone can imitate.
