The phrase is tied to Smurfs: The Lost Village, the 2017 animated Smurfs film built around the search for a hidden Smurf settlement. On soundboards, the short question has been lifted out of that adventure context and reused as a standalone reaction, which is why it works even for listeners who have not seen the film. Its appeal is simple curiosity: a direct question about a mysterious place fits discovery, travel and gaming clips, and its brevity makes it easy to drop into short edits without interrupting the scene.
