Nobody can pin 'what de fok' to a single video or creator; it spread the way most soundboard memes do, passed from clip to clip until the accent itself became the joke. The phrase is a Dutch-flavoured mangling of an English swear, and that half-profanity is what made it safe for meme compilations, gaming montages and reaction channels that wanted shock value without a hard curse. It now lives on soundboards and short-form feeds as a go-to disbelief button, usually under seven seconds long, and keeps resurfacing whenever a new cursed clip needs a punchline.
