The line comes from Downfall, the 2004 German film about Adolf Hitler's final days in the Berlin bunker, where Bruno Ganz plays Hitler discovering that Hermann Fegelein has deserted his post. The scene became the centre of the Downfall parody phenomenon in the late 2000s, when creators on YouTube kept the original audio and added invented subtitles about everyday failures, arguments and pop culture. That format spread far beyond the film itself, and the shouted name survived as shorthand for blaming an absent person when everything goes wrong.
