NY Giants Lineman -- TROLLED BY JETS FAN ... At NYC Bar

So, a couple of New York Giants football players walk into a bar ... and what happened next was pretty funny.

Offensive tackle Justin Pugh, Jason Pierre Paul and a couple of their teammates hit up Bounce Sporting Club in Manhattan ... when a group of bros invited the guys over for a shot.

Pugh took 'em up on their offer ... but as soon as he pounded the booze, one of the bros turns to the camera and reveals his true colors ... hunter green and white.
