My dad traveled overseas for business selling Machinery as he could speak other languages and the boss wanted him to go to interpret the transactions. In Italy he met a good friend Mario and talked about family alot, so from what Mario gathered from my dad...Mario gave me the nickname "Sonocativo" which to my understanding means: Thats right, I'm Bad !(eg: troublemaker, a**, ect...lol ) I never was a troublemaker but was a very tough, no nonsense person growing up, fighting alot when people cut me down... So it pretty much stuck, I was SONOCATIVO everywhere I worked, name on hardhats, lunchboxes, I liked it.
