The exact source of this clip is not clearly documented in its listing, so it is best understood as a short online reaction sound rather than a line tied to a single verified scene. Phrases delivered with this kind of startled disbelief travel easily across short-form video, where creators reuse them to punctuate surprising reveals and absurd moments. Its under-two-second length makes it easy to drop into edits, duets, and commentaries without interrupting the flow. That portability, rather than one famous appearance, explains why it keeps appearing whenever something looks too strange to explain.
