Since Ashley Darby’s birthday party felt a little juvenile (at least to some of the other housewives), Karen Huger decides to throw her own event on this week’s “Real Housewives of Potomac.” It’s a cruise and the theme is BYOM: Bring Your Own Man.

Of course, Ashley brings her husband Michael, who’s an Australian millionaire. While wearing a pirate hat, he gets along great with Karen and her husband Raymond. Essentially it’s all smooth sailing … until he commits the biggest blunder of the night.

As the evening wears on, Michael gets a little too comfortable (read: drunk) and decides to go for a swim. Just as he begins to unzip his pants to do so, everyone flips out. While Katie Rost says, “I love Australian people – they’re so wild and crazy,” that’s not quite the same reaction the rest of the group has.

Gizelle Bryant says, “If there was ever a party foul, this is it. Pull your pants up.” While Karen is equally angry, saying, “Not at my event! Your pants stay up. They don’t come down.”

Luckily, Karen doesn’t blame Ashley though. “I can’t fault Ashley for her husband’s actions. However, it doesn’t make her look good,” she says. “She needs my help.” Looks like this is just the start of the etiquette queen taking Ashley under her wing.

Twitter had pretty mixed reactions to this “RHOP” moment, but Gizelle’s response totally takes the cake.
