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 sometimes pronounced 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
"What a fugghead."
" Uh, you're a fugghead."
"Look at that fugghead."
"FUGGGGGGGGHEAD!"
