The phrase is tied to Sapobully, whose repeated delivery of Sono il king delle droghe turned a single boast into a shareable meme clip. Circulating mainly through Italian soundboards and short-form edits, it became a shorthand for mocking self-styled toughness, especially when the claim sounds bigger than the person making it. Its appeal is in its brevity and repetition: the line is easy to recognise, easy to drop into a joke and easy to quote in comments. That combination has kept it in rotation for Italian meme editors long after its first circulation.
