The line comes from the Italian dub of Stanley Kubrick's Full Metal Jacket from 1987, where Gunnery Sergeant Hartman, played by R. Lee Ermey, torments new Marine recruits during basic training with relentless verbal abuse. In the original English version he uses a string of animal and weight based insults, while the Italian version preserves that brutality with the walrus comparison. The clip spread through Italian meme pages and soundboards as a shorthand insult, kept alive because Hartman's delivery is instantly recognisable even to viewers who have never seen the full film.
