The clip comes from a comedy sketch by Quebec humorist François Pérusse, identified in its file information as Alexandre consolé par Monsieur Bonheur. Pérusse built a long career on short, absurdist French-language radio sketches built around wordplay, deadpan voices and everyday characters caught in ridiculous conversations. A single questioning word fits that style perfectly, because it can be lifted out of context and still make sense. Shared as a short audio file, it has become a handy French reaction sound for memes, edits and messaging, where one puzzled word is often funnier than a long explanation.
