This clip is mainly shared online as a short reaction sting rather than for a widely documented film or TV origin. Its label points to a nosy or startled neighbor style response, which fits how creators use it in skits, surveillance jokes and awkward reveal edits. Because it is so brief, it spread easily on short-form video platforms and in soundboards where fast, recognizable reactions are useful. It stays popular because a quick gasp can sell surprise in less than half a second.
