The losing horns come from The Price Is Right, the long-running American television game show where contestants bid on prizes and play pricing games. When a player fails to win a showcase or a game, the show plays this deflated brass sting instead of celebratory music, a contrast that made it shorthand for losing on television. Clips of the sound spread through reaction videos, game show compilations and meme edits, where it now sits alongside other fail stings like SpongeBob Fail and the dramatic dun dun cue. It endures because the disappointment is instantly recognisable even without seeing the show.
