I wouldn't call it a "diss" but there was some animosity there towards 40... at least it seemed that way
if he had just said only 40 capitalized of hyphy and left it at that... it would be cool
but he said this...
"Niggas be selfish, man. I'll put it like this: You've got money, right? But if somebody under you that don't got no money, but got a lot of talent and got something that you can exploit to get money from, and you use your money as a chain and as a channel to exploit his talent, that's selfish. Because what you can do is you can take your money and you can help him out. But instead you want to help yourself out with his talent. So you're using him only for self benefit. And that's selfish, man."
I'm sure Fab and 40 are still cool... and Fab was probably just speaking out of frustration... but I did see it as some disrespect towards 40
