The French title détecteur de mensonges simply means lie detector, and the clip circulates online under that name as a short reaction effect rather than as a scene from a known film or show. Its appeal comes from the familiar polygraph idea, where a machine supposedly exposes dishonesty, reduced here to a single buzzer anyone can understand without context. Shared on soundboards and in short form edits, it has become a quick shorthand for disbelief, used whenever a statement in a video, chat or stream sounds too convenient to be true.
