A bunch of jabroni's

Old Kadizzle grew up in Wheeling, West as they say "by God" Virginia.  Wheeling had a lot of different ethnicities.  With Italians, Poles, Syrians, Orthodox Greeks,  and every other brand of human there were many words that floated around.  One of those words was jaboni.  It must have been Italian. As a kid I heard the word.  Never knew what it meant, but figured it was not good.  Looking up the work the common use is to call someone a jabroni and you are calling them a loser.
