"I'm not some pretty f*****g helpless princess in distress," say the girls, who are aged from six to 13. "I'm pretty f******g powerful and ready for success."
The video is unflinching, there are no bleeps to protect the easily offended as the potty mouthed princesses drop the f-bomb 15 times in the name of another f-word that some people think is equally offensive - feminism.
In one particularly jarring moment, the girls say that one in five women will be sexually assaulted or raped, before one asks: "Which one of us will it be?"
Video producer Mike Kon comments: "Some adults may be uncomfortable with how these little girls are using a bad word for a good cause. It is shocking what they are saying, but the real shock is that women are still paid less than men for the same work in 2014, not the use of the F-word.
"The big statistic that one out of five women are sexually assaulted or raped is something society seems to find less offensive than a little four letter word and we love how these girls draw attention to that imbalance."
The video ends with a woman asking: "Instead of cleaning these girls' mouths out with soap maybe society should focus on cleaning up its act?"
FCKH8 is a T-shirt company with a social change mission: 'To arm thousands of people with pro-LGBT equality, anti-racism and anti-sexism t-shirts that act as mini-billboards for change'.
The video was made to raise awareness of FCKH8's t-shirt fundraising campaign. The company will donate a third of the price of each t-shirt sold as part of the campaign to anti-sexism organisations and projects.
As you might expect, the reaction to the video is mixed, with some commenters congratulating the girls and their parents for breaking the taboo of swearing for the cause of gender equality. But others are outraged that parents would let their young daughters swear for any reason.
