The sound comes from Stanley Kubrick's 1987 film Full Metal Jacket, where R. Lee Ermey plays Gunnery Sergeant Hartman, the brutal Parris Island drill instructor training new Marine recruits. Ermey had served as a real drill instructor, and his improvised tirades became the film's most quoted element. Short clips of his insults, including Italian dubbed versions, later spread across forums, videos and soundboards, where Hartman's voice is now shorthand for an exaggerated, merciless scolding that is more comic than genuinely threatening.
