The losing horn is the famous sad trombone sting that dates back to early twentieth century vaudeville, where a trombonist would slide downward to mock a bad act. Television game shows adopted it as the official sound of failure, playing it whenever a contestant lost, and it became a fixture of comedy records and cartoons. Online it exploded as a reaction meme layered over fail compilations, gaming clips and sports bloopers, often paired with the wrong answer buzzer for maximum humiliation or swapped for the emotional damage meme when the roast needs to sting more.
