The phrase itself is ordinary formal French, commonly used to politely set a boundary when speaking, writing or answering questions. As a standalone soundboard clip it has been lifted out of that everyday context and reused online as a short reaction drop, especially in French-speaking meme and chat spaces. Its appeal comes from the contrast between the polite, almost academic wording and the casual situations it is pasted into, from trivia mistakes to confused group chats. That contrast keeps it reusable without needing a specific scene or speaker.
