The phrase is everyday Portuguese, literally asking where they are hidden, and its online life comes from that plain, recognisable wording rather than a confirmed film or show source. Short question clips like this circulate on soundboards and in edited videos because they can be dropped into many different searches, chases and hide and seek setups without needing setup. Portuguese meme audios are widely shared beyond Brazil and Portugal as reaction sounds, and this one stays useful because the questioning delivery makes the joke clear even when the exact words are translated in captions.
