Mathieu Bevelaqua says shit its that zip Furio who was pounding at the door in season 2 . is this ignorant writers who never checked the true meaning of zip which is sicilian and thus applied it in ignorance to all italian born mafiosi in america not just to its true meaning of sicilian. Or is it purposely implanted by the writers to show the bevelaqua`s characters fumbling ignorance to proper lcn terminology?
