Last week, 19-year-old rapper Sha Ek banned Kodak Black from Sha's hometown of NYC after Kodak wouldn't let a verse he originally recorded for Dave East go on one of Sha's tracks.

"You can't come to New York, ever again.  Ever. Ever.  You're slummed out.  It's over.  Suck my dick, Kodak.  Suck my dick," the drill rapper claimed.

Yak was up north this weekend for JAY-Z's Made In America show in Philly.  Kodak wasn't able to perform the festival because he showed up too late.

So instead he popped up to New York to prove that Sha's no-fly zone was a bunch of bull.

Do you think Sha will react to having his card pulled like that, or will he fade back into the background after being humbled by Yak?
