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!!
also sometimespronounced fuckhead or fuggggggghead, this word usually pertains to someone who:
1. does stupid things
2. acts like an asshole
3. owns a ford taurus
pretty much anyone qualifies as a fugghead
