Uh Oh is a conventional interjection used to signal mild alarm or realization of a mistake, typically spoken as two quick, connected syllables. It functions as a casual, informal cue in response to an unforeseen or problematic event, often preceding an explanation or corrective action. As a proper noun in some contexts (e.g., brand or title), its pronunciation remains the same but carries a specific referential meaning rather than semantic content.
