Ignore the other definitions. It’s just Italian for “pig” and you use it the same way as in English. If someone eats too much and is a slob with marinara down their tight fitting wife-beater undershirt, they’re a “dirty gavone”; or if they throw their trash out the window on the highway “what a fuckin’ gavone!”
Me: You see that fat fuck eating the Mortadella sandwich with mustard running down his chin?
One of the greatest guys you will ever meet. He is a nice looking, clean cut young man. He has a beautiful smile. Did I mention he was tall? He has a heart of gold. Would give you the shirt off his back if you needed it. Very good natured but don't push him--explosive temper when provoked. Not a violent person--hates confrontation--but won't wuss out. Always thinks of those less fortunate. ALL AROUND GREAT PERSON!!

Wife: "get off halo right now and have sex with me!"
Husband: "not now babe..I just got gravenaded and I'm gettin' some fucking revenge."
