50 dissed Big Moe of the Screwed Up Click, and my man Z-Ro (also of Screwed Up Click) stepped up to diss 50 back, on that new Scarface track "Snitch Nigga", and on "Ready 4 War" by another group of his, S.L.A.B (Slow Loud And Bangin), and they came at him hard, but 50 aint doin nothin.
But if you could get it where 50 would hear the diss, and it was a good diss, that would be a lot of good promotion..
