The phrase comes from Portuguese speaking meme circles where short Dexter clips are reused as reaction sounds, though the exact original upload is hard to trace. Online it spread through soundboards, short video edits and chat audios, where the question format makes it easy to drop into almost any confusing situation. Its link to the wider Dexter meme keeps it recognisable, while the unfinished question lets each creator supply their own punchline, which is why it keeps being reused.
