The pull up warning is a standard terrain alert used in modern airliners, including the Airbus A220, where a ground proximity system warns the crew to climb away from rising terrain. Aviation enthusiasts and flight simulator players began sharing cockpit recordings and recreations online, and the clipped warning soon spread into short-form edits and memes. It remains popular because the short command needs no explanation, instantly reads as danger, and works equally well in serious aviation content and playful videos about sudden drops or close calls.
