Regarding the origin of his stage name, the rapper said: "Biz comes from the first hip-hop tape I heard. It was ’77, ’78, from the L Brothers. Grand Wizard Theodore was the DJ, and the rappers was Kevvy Kev, Master Rob and Busy Bee Starski. I loved Busy Bee. Busy Bee just stuck with me. My name used to be Bizzy B Markie, and after a while I put the Biz with the Markie. My nickname in my neighborhood was Markie."
