Jeezy talked about the origin of his rap name, noting that Lil Wayne and B.G. are the ones who inspired his moniker.
While speaking to ‘Rap Radar,’ Jeezy spoke to the hosts about where Young Jeezy derived from. The rapper said, “You know [the Hot Boys] had B.G., and they called him B. Geezy, Wayne, they called him Weezy.”
He continued saying, “And it was like a thing going on at the time, and people used to kinda call me that back in day because my voice was so raspy in school. So I was like, ‘Yo, I’m just gon’ go with this.” The rapper noted the only nickname he ever had was “Lil J,” which his grandmother called him. Watch above.
