My username is one of many nicknames given to me by friends. With a name like Rocco, you hear many. I believe the first time I heard Rock Daddy was actually to refer to my beat up pickup truck in High School. I'd give my friends a ride in the "Rock-Daddy". It had a nice ring to it, so I started using it for a username. Other nicknames include but are not limited to Roc, Rockus, Rococo, Count Rocula, Doc Roc, Rocco's Modern Life, and Rocco P. Coltrane, among others.
