So last year, Madonna Instagrammed her armpit hair.
A few months after that, women started sharing photos of their dyed armpit hair.
In comes Miley Cyrus last month with her own armpit hair.
Bruce Willis' daughter posted her own armpit hair to Twitter around the same time.
Then, three weeks ago, Lena Dunham posted this note that including "grow armpit hair" as a goal for the summer.
This month, Dunham's Girls co-star Jemima Kirke showed up on a red carpet with some very elegant tufts of armpit hair.
Kirke also tweeted some important retro pit-spiration.
Now, most recently, Chinese women are getting in on the trend.
Xiao Meili, a women’s rights activist, pictured below, organized the “Women’s Armpit Hair Competition” on Chinese microblogging site Weibo.
Armpit hair has been so stigmatized for Chinese women that they “would rather fall down on buses than to hold something and expose their armpit hair,” Xiao said.
The women who joined the competition seriously got into it though.
The winners of Xiao's contest will be those who get the most reposts, likes, and comments on Weibo.
