The line comes from Full Metal Jacket, Stanley Kubrick's 1987 film about Marine recruits in basic training, where drill instructor Sergeant Hartman, played by R. Lee Ermey, subjects his platoon to relentless verbal abuse. In the Italian dubbed version his insults sound even more blunt and theatrical, which helped the clip circulate among Italian meme pages and soundboards. It endures because Hartman remains a shorthand for merciless authority, and the pollution insult is so exaggerated that it works far beyond its original military scene.
