Move over, boys.

Celebs are taking a stand against manspreading -- the annoying habit men have of obnoxiously spreading their legs too far apart while sitting, especially on a public bus or train -- by uncrossing their legs.

#Womanspreading is the new female power stance taking over Instagram where ladies crouch or sit down in an open leg position and casually vogue for the camera.

“Women are realizing they don’t have to conform to any so called ‘appropriate ladylike’ way to sit,” pop culture expert Valerie Greenberg tells Moneyish. “It’s a movement that says we’re equally powerful.”

The power pose challenges the motives behind manspreading, which men do either to show dominance or because they think it’s actually comfortable, despite being wildly inconsiderate. The practice of males taking up too much room for no apparent reason became so commonly mocked, the MTA in New York City put up signs urging men to close their legs. “Dude...Stop the spread, please. It’s a space issue” one reads. The term was even added to the Oxford Dictionary in 2015.

Now #Womanspreading is having a moment as supermodels like Bella Hadid, Emily Ratajkowski and Chrissy Teigen blatantly ignore the rules of sitting pretty, instead sprawling out wherever they please. And many other women have joined the relaxed movement with similar social media posts.

“With the dress code years ago, you had to sit with your legs closed and your feet crossed at the ankle or at the knee because of the simple fact that that women wore skirts. Pants were not worn for many years so that’s where that “ladylike” notion came from,” etiquette expert Karen Thomas tells Moneyish. “Now, gender-neutral etiquette is really coming into play. It’s becoming acceptable to sit with your legs uncrossed in a casual setting with pants.”

Vogue all you want on the train, in a coffee shop or on the street, but when it comes to the boardroom, Thomas urges that everyone -- whether you’re Bradly Cooper or Kendall Jenner -- sit with their legs closed.

“From a business standpoint, women and men should keep their legs closed. It’s always preferred to be professional in stance and in body language,” Thomas says.
