NFL's Victor Cruz -- Pitches Tent In NYC Street ... Drivers Pissed

Here's a surefire way to piss off New Yorkers ... stop traffic in the middle of a busy day (on a super busy street) for a camping photo shoot in the middle of the street!!!

That's what NY Giants WR Victor Cruz did Thursday ... pitching a full-size camping tent in the middle of 6th Ave. for a funny photo shoot with celebrity jeweler Mr. Flawless -- and TMZ Sports has the footage.

Watch the video ... you can hear the pissed off drivers leaning on the horn while the two try to look comfy in their urban camping setting ... complete with firewood on the asphalt.
