This line is best known from the Warcraft real-time strategy series, where it plays when a player tries to spend resources they do not have. It became a long-running gaming meme because the phrase is short, instantly readable, and easy to apply outside strategy games. Creators still use it for jokes about money, materials, stamina, or any shortage in games and everyday life. Its staying power comes from how clearly it turns a simple resource check into a memorable punchline.
