This clip circulates online as a standalone reaction sound rather than as a widely documented excerpt from a film or television show, and its exact original recording is not clearly credited in the listings that share it. Its appeal comes from the way the familiar phrase is stretched far beyond everyday speech, turning a simple refusal to believe something into a performative joke. Editors reuse it because it is instantly understood without context, works across pranks, gaming, commentary and reaction videos, and still lands when a moment needs exaggerated shock.
