The losing horn comes from The Price Is Right, the long-running American television game show known for its bright sound cues and contestant reactions. Online, this particular horn spread far beyond the show because it communicates failure in under three seconds. Creators use it in compilations, sports edits, livestream moments and meme videos whenever something goes obviously wrong. Its staying power comes from how instantly recognizable and universally readable it is, much like a classic buzzer in other game show style edits.
