Last season on The Real Housewives of New York City, Ramona Singer and best buddy Sonja Morgan weren't thrilled when Aviva brought her hubby along on a girls vacation, for obvious reasons. Aviva's reaction was anything but apologetic. She flipped out and called them "disgusting" and "white trash." Funny thing was, the women had to google the white trash reference to understand the insult.

It was the battle of the booty on The Real Housewives of Atlanta. When Kenya and Phaedra couldn't come to an agreement over Phaedra's Donkey Booty fitness video, Kenya decided to make one of her own. The insults flew over who had the booty to get the job done.

The entire family has been dragged into this one. Parents, in-laws, and children on The Real Housewives of New Jersey. The worst was the rumor that Teresa started the story that her sister-in-law Melissa was a stripper who cheated on husband Joe. Now Melissa looks like she's begging Teresa to stop.

Vicki and Lauri threw down on the ski slopes after Vicki admitted she and her former husband both cheated on one another. But Lauri took it a step further by spreading the rumor that Vicki had not one, but multiple partners in adultery. No surprise that Vicki took offense.

First Carlton took offense to Kyle killing a bee, then to her asking about her tattoo. Now it's spiraled into fight over differing religions and we doubt this feud is anywhere close to over on The Real Housewives of Beverly Hills.

Joanna took offense when Lisa got drunk and called her a whore. But by the end of the season Joanna was in full on bitch mode and Lisa was reduced to tears on The Real Housewives of Miami.

Teresa started it by dissing Caroline's son's idea for a stripper car wash in her cook book. Then Caroline called Teresa superficial. Now neither one wants to be in the same room with the other on The Real Housewives of New Jersey. Is this what has Caroline leaving the show?

Slade was the king of insults on The Real Housewives of Orange County as he threw jibes at almost everyone but calling Vicki Miss Piggy was a particularly low blow. To retaliate, she created her own bacon-flavored vodka and shared some to Slade.

The former friends went at it during the last The Real Housewives of Miami reunion show. Joanna had been vocal about her new husband's lack of interest in the bedroom giving Adriana an opening. The low blow came when Adriana said Romain's real issue was having a "limp penis." We doubt that Joanna or Romain will forget that insult any time soon.

They might be chummy now but Brandi and the Richards sisters have several rounds starting with the day Brandi hobbled into a party on her crutches and Kim and Kyle slipped into mean girl mode on The Real Housewives of Beverly Hills.

Lea was hurt when she found out long time girlfriend Adriana had lied to her about being a single mom when she had in fact been legally married for several years. But Adriana turned the tables and tried to put all the blame on Lea for being a bad friend instead of owning her lies on The Real Housewives of Miami.

No, she hasn't actually thrown down with daughter Kandi's fiance but she's tried to beat down Kandi's friend Carmon when she stood up for the pair. Not to mention Mama supposedly offered money to anyone who could get pictures of Todd with another woman. Poor Kandi's got some serious mama drama on The Real Housewives of Atlanta.
