Lo scudetto is the informal name for the Serie A championship in Italy, represented by the shield worn by the defending champions. Calling it cartonato, or cardboard, is a long standing insult used by rival fans to suggest a title was gifted, undeserved or won without real merit. The phrase is especially aimed at Inter in online football banter, where short chant clips circulate among Juventus, Milan and Napoli supporters. Posted as a soundboard clip, it survives because it compresses years of rivalry, title disputes and stadium teasing into one instantly recognisable taunt.
