The title is a mashed up spelling of deja vu written out the way the clip sounds, with the syllables stuck together and repeated. Sounds like this spread as short soundboard clips and social video edits, where a six second loop is long enough to build the joke but short enough to replay instantly. It stays popular because the concept is universal, anyone recognises the feeling of seeing or hearing something identical again, so creators reuse it across memes, reaction videos and everyday coincidence posts without needing any extra context.
