The line comes from Full Metal Jacket (1987), Stanley Kubrick's Vietnam War drama, where Gunnery Sergeant Hartman, played by R. Lee Ermey, demands to know which recruit dared to speak out of turn during a barracks inspection. The German-dubbed 'Wer hat das gesagt?' preserves the sergeant's clipped menace and has become a standalone reaction clip on soundboards, where it is used to mock-seriously interrogate anyone caught talking. It circulates alongside other drill-sergeant memes and pairs naturally with a fail sound when the culprit gets exposed.
