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.

Brazilian truck driver saying what the fuck in heavily accented English as quetafoque, a short viral reaction clip used for confusion and disbelief.
This is a very short clip of a Brazilian truck driver trying to say what the fuck in English, which comes out as a drawn out quetafoque man. The delivery is loud, confused and completely sincere, with the heavy accent turning a common English swear into something absurd and instantly quotable. It lasts under two seconds, so the shock hits immediately with no build up. Viewers use it as a pure reaction to something unbelievable, stupid or unexpected, where the mispronunciation makes the disbelief feel funnier than the original phrase ever would.
