A derogatory American Mafioso term for Sicilian Mafia. Unless you are the Godfather of La Cosa Nostra, I wouldn't even say zips around a pizza pie. They were Sicilian immigrants or part of the Italian mafiosi who had zero fucks to give. They would kill anyone who wasn't a part of their plan. Drugs and crime ruled their underworld. Think of the 1997 film, Donnie Brasco.
