The phrase comes from the German film Downfall, released in 2004, where Bruno Ganz plays Adolf Hitler in his final days in Berlin. Clips from the film became a long-running internet meme format, especially subtitled parodies that replaced the original dialogue with jokes about unrelated topics. The shouted order fits that format because it is short, recognisable and easy to drop into a new context. Louder, boosted versions later spread on soundboards and short-form video, where creators use it as a punchline for strict authority, failed plans and exaggerated discipline.
