You can refer to members of The Royal Family as many things.
Spoiled, perhaps. Out of touch, maybe. Old fashioned, almost definitely.
But there's one insult that rises above the rest.
There's one word swipe you can take that will serve as a legitimate burn, something that will cause the Queen to look up from her Cream of Wheat and give you a true stink eye.
And a friend of Prince Charles just used this term to describe Meghan Markle's loved ones.
Speaking to The Daily Mail, Nicky Haslam - was born to one of Queen Victoria’s goddaughters, went to school with Prince Charles and socialized with Princess Diana - took aim at Markle's family and bashed them as "frightfully common."
This may sound relatively harmless and totally innocent, but think about it for a moment.
Is there anything worse you can say about someone associated with the Royal Family than referring to him or her as a "common" person?
We really don't think so.
Meghan, of course, married Prince Harry on May 19.
Of all the details surrounding these monumental event, two things stood out, both of which Haslam had an opinion on.
First, Thomas Markle did not attend her daughter's wedding; partly due to health problems and partly due to embarrassment over a paparazzi photo scandal in which he received money in exchange for a few not-exactly-candid poses.
Markle was crushed by her dad's absence.
But Haslam was grateful he didn't show up for the big day.
"It would have been awful if that huge lump had been there," he told the aforementioned British newspaper.
The second thing to really note about this Royal Wedding was, naturally, Markle's wedding dress.
What would it look like, folks wondered prior to the nuptials? Who would design it?
For the most part, reviews for the reviews of the Givenchy gown were positive in the hours and days after the ceremony, but Haslma has no idea why.
"I didn’t very much like her dress," he says here. "It didn’t fit, among other things. It should have been made of thinner stuff, it seemed to be made of concrete."
(Pop singer Katy Perry, we might as well add, also slammed Meghan's dress, saying "I would have done one more fitting.")
Nicky Haslam clearly sucks and isn't really worth spending too much time on.
But sources tell Us Weekly that those even closer to the Royal Family are frustrated by Markle; or, to be more specific, frustrated by Marke's father and the interviews he continues to give.
"Thomas is walking a fine line,” a source tells this tabloid. “This blabbing needs to stop if he wants to maintain any relationship with Harry and Meghan.”
Late last month, Thomas actually hurled some shade at Queen Elizabeth, wondering why President Trump has had a chance to meet her, but he has not.
"If the Queen is willing to meet our arrogant, ignorant, and insensitive president, she has no excuse not to meet me," Thomas told TMZ, adding:
"I'm nowhere near as bad."
On that point, we're guessing even Haslam would agree.
