D12 

Its a group that consists of Eminem, Bizzare, Proof, Kuniva, Mr Denuan Porter, and Swift. They all have Alter egos that makes up for the other six that was missing.

D12= Dirty Dozen OR D12=Detroit Twelve. It stands for both to all you faggots out there who argue about it over the net with people you dont even fucking know.
