The clipped spelling donchu turns don't you wish into one searchable phrase, which is how the sound travels on soundboards and short video apps. Users post it as a stand alone punchline rather than a full song, so the hook has to be recognised in the first seconds. It keeps circulating because the line works without context, fitting outfit checks, car edits, sports highlights and confident entrances. New uploads keep the same short title, making the clip easy to find, save and reuse in reaction edits.
