The womp womp itself is a long-running comedy shorthand for disappointment, borrowed from the drooping sad trombone heard after a joke falls flat or a contestant loses. This walkie talkie version keeps that same letdown signal but wraps it in radio noise, which makes it feel more like a failed transmission than a stage gag. Short meme sounds like this spread through soundboards and short-form video because they need no explanation, and this one survives because the joke lands in under three seconds.
