The source of this line is not documented, so it circulates mainly as a standalone reaction clip rather than as a recognisable scene from a film or show. Its appeal comes from the wording itself: a promise made to a child sounds especially unfair when it is broken, and that makes the line easy to reuse across unrelated videos. Creators paste it over gaming clips, shopping fails and everyday arguments, where the short length lets it work as a quick interjection. Because it needs no setup, it has stayed useful for short-form edits that rely on an instant emotional reaction.
