The whomp whomp phrase comes from the sad trombone tradition heard in vaudeville, cartoons and television game shows, where a muted brass slide mocked a performer or contestant who had just failed. Online, the short clip was cut down for soundboards and meme edits, sitting alongside the sad violin and the wrong answer gameshow buzz as a go to failure cue. Its four note shape is instantly recognisable even without an image, which is why creators still reach for it when a moment needs a clear, comic sense of disappointment in under two seconds.
