I heard this was recorded in December. The intro jab was prolly referring to the Rap about it podcast considering its a Max B track and that's around the time frame they rapped over his beats and Fab sent his jabs.
My theory is that the 4 F U's at the beginning would align with Jim, Maino, Fab, and East. The timing of the release of course has everyone thinking its T.I. and fam related but I don't think 50 gives AF enough to give T.I. sons any traction from a record plus it's been 3 of them rapping, not 4
