Nems F*** NY Knickerbockers!!! Mr. Bing Bong Can't Sit in Nosebleeds!!!

Gorilla Nems isn't feeling appreciated by the New York Knicks after lending them his trusty catchphrase ... and he's flipping them the bird as a staff, organization, and entire crew!!!

Bootleg Kev struck an apparent nerve with Nems when he asked if he gets free Knicks tickets since flipping his "Bing Bong" track into a remix for the team, and the Coney Island rapper went off.

Nems claims the NYK have "disgusting" business tactics, and are snakes in the grass ... and he says they make him jump through hoops to catch any hoops action at MSG.

He claims the team tried to offer him crappy seats after he participated in a celebrity b-ball game, but Nems says he wants courtside or nothing.

We gotta say, that's a pretty tall order -- everyone knows those Garden seats are always filled with A-listers -- and yet, Nems feels the team owes him a Spike Lee-adjacent seat.

Knicks fans know the "Bing Bong" soundbite well ... it plays in MSG every time the team makes a 3-pointer. You'd think that would make Nems a life-long Knicks fan, but that relationship's clearly soured.

Might be time to head over to the home of Brooklyn Nets.
