The term 'Capos' is a shortened version of the Italian word 'capo di tutti capi', which translates to 'boss of all bosses'. It is used to refer to a high-ranking member of a crime organization, such as the Mafia. The term 'DONS' is also used to refer to a leader of a crime organization, and is derived from the Spanish word 'DON', meaning 'LORD' or 'MASTER'. Both terms are used to describe the same type of person, but 'Capos' is more commonly used in the United States.
