Joe Gorga is officially one of those parents after losing it on the referee of his son's wrestling match -- a nose-to-nose showdown that ended with Joe getting booted outta the gym.

In video, obtained by TMZ, Joe can be seen losing his cool Saturday at Parsippany Hills High School in NJ -- where his son Gino was in the middle of a match that ended with him getting pinned by his opponent.

That made Dad leap from the stands and charge at the ref, but not before staff members and other parents jumped in to make sure it didn't turn into a brawl.

As Joe's led away, the ref blows his whistle in disgust and repeatedly orders him to leave the gym altogether for the remainder of the wrestling action.

Days later, Joe's still heated -- a rep for the 'Real Housewives of New Jersey' star tells TMZ Joe felt the ref made some bad and unfair calls during the match, and Gino's opponent was mistreating him ... at least in Dad's eyes.

The rep says Joe never had any intentions of hurting anyone or getting physical. He just let his emotions get the best of him.

In the end, the rep says Joe believes his son's opponent was conducting himself in an unsportsmanlike manner throughout the match, and the ref let it slide.

We're told Joe's proud of how his son handled everything ... labeling him a class act despite his own emotions getting the best of him.

Eyewitnesses at the event tell TMZ Joe was immediately ejected from the gym, and he left without any further duress, while the competition continued.

Hard to say cooler heads prevailed, though, based on the video.
