Big Fendi, the "Come Up DVD" former manager of Nicki Minaj, got into a heated verbal exchange with Sub 0 in what appears to be a clothing store.  Things turned physical real quick after Sub 0 hooked off on Fendi before stepping back and saying, "let's step outside!"  Fendi maintained his balance, however, and came back with a vicious combo of hard hitting uppercuts to Sub 0's face.  The brawl was broken up shortly after when the two became tangled in a grappling match.

Watch the beef unfold above.
