50 Cent has been rocking with his troll son Teka$hi 69 for a minute now.
So when Fif saw that some folks were accusing 69 of swiping a freestyle, he Instagramed on over to defend him -- and ended up shading JAY-Z in the process.
"Damn jay z did that to big a hundred times," Fif wrote in the comments of the post suggesting 69 swiped bars.
As for the bars 69 allegedly stole ... they come from NYC rapper Yoppy Montana.
Judging from this Yoppy IG post, in which he and 69 have a friendly FaceTime, it's more like the bars were borrowed.
