The phrase began as the famous jingle slogan for SpaghettiOs, the canned pasta introduced by Campbell's in 1965. Generations grew up hearing uh oh SpaghettiOs in television commercials whenever a messy spill happened. The line later became a general catchphrase for minor accidents and was widely clipped and shared online as a reaction sound. Its link to The Simpsons in soundboard collections helped keep it circulating among meme editors, who reuse it whenever a character makes a small, embarrassing mistake.
