Kiss My Grits became famous on Alice, the CBS sitcom that ran from 1976 to 1985 and starred Linda Lavin. Waitress Florence 'Flo' Castleberry, played by Polly Holiday, used the line as her regular put-down, and it quickly moved beyond the show into everyday slang and merchandise in the late 1970s. Holiday left for the short-lived spinoff Flo in 1980, but the phrase stayed tied to the original series. It survives on soundboards because the wording is distinctive, family-friendly, and instantly signals Southern sass.
