The clip comes from a Brazilian truck driver recorded speaking English, where his pronunciation of what the fuck became written and shared as quetafoque. It spread mainly as a WhatsApp audio and short reaction sound in Brazil, then reached wider meme pages that reuse foreign accented English for comedy. Its appeal is not a known movie or show but the everyday humor of a language barrier, which is why it survives as a quick disbelief reaction rather than a longer catchphrase tied to one video.
