Jersey Shore Family Vacation Pt 2 got heated last night when the girls went out for a low-key, “classy” wine night. The only problem is that some douche-bag decided to call Deana fat.

What’s really messed up is that Deena Cortese is pregnant. Read on to find out why Ronnie Magro is ready to fight…

CelebNReality247.com reports that the gloves came off on Jersey Shore: Family Vacation this week but not between Ronnie Jen Harley.

Things got heated at a wine bar in Jersey after JWoww, Snooki, Deene, and Angelina have a run in with a cooch.

The Jersey Shore girls ended up drinking and eating “17 pounds of cheese.” Jenni joked that she felt fat, but that is when the cooch in white linen pants at the bar called Deena Cortese fat on their way out of the restaurant.

The cooch ended up uniting the girls together and got JWoww in fight mode.

Jenni told the camera

Oh, hell no! You can come after me all day, but the moment you talk about my friends, game over. I will annihilate you.

JWoww charged at the dude and asked him:

Were you just making fun of a pregnant girl?!

Without missing a beat, he admitted:

I was. I did. I called her fat.

Jenni FIRED BACK yelling in the loser’s face:

You’re a piece of shit! You’re a f-cking bitch, bro! You wanna get whooped by an f-ckin bitch?! This is what’s wrong with America. Piece of shits like you going after pregnant girls. He’s lucky that I’m full of brie and have Louboutins on.

The Cooch MESSED with Rnnie Magro, NOT SMART!

It didn’t end there. The next night the cooch messed with the wrong person. Nicole was the first to notice him why they sat at dinner before hitting the upstairs club with the guys.

Then cooch started circling the table and stopped to shake Mike’s hand. Unaware, Mike said hello and Nicole, JWoww, and Deena told him to leave.

They Guidos and Guidettes moved upstairs but the cooch wouldn’t let up he popped up and flipped the Jersey Shore fam off, so Pauly got up in his face. The Cooch got 86’d but Ronnie was downstairs.

Why Ronnie Magro Readies to Fight:

Ronnie stepped in and the cooch came up to him and started talking mess. He starts telling him he was a loser and then called Ronnie “babe” and touched his chain.

Ronnie was instantly pissed a got readie to unleash month of anger on him, but dude got thrown out.

Magro heads outside to fight, but a nemisis of Angelina’s is out there ready to fight. Things escalate and JWoww joins in to defend Angelina.
