A rapper who is associated with Jay-Z. Jay-Z appeared on one of Jaz's earlier songs "Hawain Sophie", in the year 1989. Jaz has continuosly blamed jay-Z for biting off his name, and disrespecting him, thinking he's now doing this because Jay-Z got a big head when he became famous. And he did, he continually dissed Jaz. the more money Jay-Z got, the more he began to forget about his fellow Brooklyn rapper.
Jaz-O was devistated by Jay-Z's disrespect, so when Jay-Z offers him to finally be on some of his songs, suck as Bring It On, off the Reasonable Doubt album, he tries desperatley to Out-Do jay-Z, to prove he's better and fails. But he did out do him on the song Nigga Who, Nigga What.
