'Jersey Shore' Kids: The Next Generation of Fist Pumpers

"I'm not gonna show you my f--king tit!" Pivarnick hurls across the table.

This saga is far from over.

In a sneak peek of Thursday's episode of "Jersey Shore: Family Vacation," a dinner among the roommates gets turned upside down when Jenni "JWoww" Farley accuses Angelina Pivarnick of lying about a nipple piercing.

Of course, we know the root of the issue is what Angelina says she didn't do with Jenni's 24-year-old boyfriend, Zack Clayton Carpinello, who claims Angelina kissed him during the group's boozy night out in Las Vegas. Angelina's version of events, however, is that Zack grabbed her hip/butt area in a way that made her feel "uncomfortable."

"How much do you commit to a lie?" Jenni asked Angelina while sitting at the dinner table, prompting Nicole "Snooki" Polizzi, Vinny Guadagnino, Pauly D and Ronnie Ortiz-Magro to let out a collective "OOOHHH!"

"How much do you commit to a lie?" Angelina fired back, causing Snooki to shriek even louder, and Pauly and Vinny to shoot up from their seats and run around the table.

"I don't commit to shit," Farley maintained. "I would be the same way if I felt guilty, too. But it's fine." Pivarnick reiterated that she "never tried to kiss" her co-star's boyfriend.

Farley repeated numerous times, "But you did! But you did!" as Pauly did somersaults in the other room. "And then you wanna lie about a nipple piercing and make it a big thing!" she continued. "You actually committed to that lie, too. Fully committed. Fully committed. Do you have it pierced?"

Trying to be heard, Angelina begged, "Lemme just get a word in. Hold on! Yes, I do. I don't have to show you shit. I'm not gonna show you my f--king tit! It's not this one, it's this one."

In his confessional, an elated Pauly said, "It's so crazy how a pierced nipple just sparked WWIII over here. Insane! A pierced nipple started it!"

"I'm not the one that's kissing other men, showing my vagina and oiling up somebody else..." Jenni began to say to Angelina, who cut her off. "I would never kiss somebody else, girl. I don't even think your man's hot!"

Deena Cortese, who's been Angelina's only real friend in this mess, frantically reminded her that "this wasn't what we talked about in the car." But Pivarnick maintained she had to defend herself because Farley was "comin' at me hot right now."

"Not comin' in hot! You're the one that pointed to me and said, 'I have a problem with you, and I have a problem with you,'" JWoww fired back, interrupting Angelina's clarification to ask, "Are you f--king stupid?!"

No one was happier to not be involved in the drama than Ronnie, who smiled as he ate his broccoli and drank his canned Pellegrino, all while the back-and-forth between his roommates intensified.

"I'm not stupid!" Pivarnick shouted.

"You are stupid!" JWoww replied. "You sit here and disrespect your man with half my f--king roommates! ... Then you look at everyone like, 'I don't understand why I have problems in my relationship. I don't understand why Chris has such anger issues.' Here's the reason, Angelina: Stop disrespecting your man!"

Pivarnick then went where Farley's tried all season not to go. "What about your f--king divorce that f--king happened that you don't want us to talk about?!"

Fired up, JWoww replied, "Because I respect my kids, and I respect my ex-husband! That's how you get a divorce!" Pointing at Ron, she added, "And you take note, too, motherf--ker!"

In her confessional, Angelina called Jenni a "deflector," a "hypocrite" and a "f--king bullshit artist."

"She's lying right now about me and her 24-year-old sperm bank f--king donor boyfriend," she said angrily to the camera. "Sorry, don't want your man!"

"Jersey Shore: Family Vacation" airs Thursdays at 8 p.m. on MTV.
