English slang loan word from Italian, meaning '"Big Shot", originally from WWII, when the Italians used it for the 90 mm artillery, "Big 90 (mm)". the phrase made popular in the film "The Godfather", when Vito tells his son Michael that he wanted him to be an important person, like a Senator, and Michael responds, "another pezzo-novanta", usually used pejoratively.
