The source of this recording is not documented, so it is best understood as a short Spanish meme audio that circulates as a reaction clip rather than a line from a known film or show. Its humour comes from the Spanish pattern of comparing something to an object to stress how fake it feels, here a CD, and the brief delivery makes it easy to reuse. Creators share it in short videos and messages whenever they want a quick, playful way to question what they have just seen, which keeps the phrase useful long after any trend has passed.
