Sicilian for bastard (literally "son of a whore"), similar in idea but more pejorative than S.O.B. The sing-song (or prosody) is critical.

It sounds great when pronounced correctly, very cathartic. See that scene in Godfather 2 where DeNiro stabs the old guy who killed his mother.The old guy says it right!!
