Think the F-word is a dirty word? These little girls can think of a few that are worse — like “pay inequality” or “rape and violence.”

But there’s a reason for their potty-mouthed exclamations — these young girls, dressed up in princess costumes, are cursing to protest inequalities that are even more shocking than curse words. The video was made by FCKH8.com, a for-profit company that produces clothing that advocates for social change. And while FCKH8 is famous for equality-themed T-shirts like “Some Chicks Marry Chicks” and “Straight Against Hate,” this particular video is meant to promote its feminist line, with T-shirts that say things like “This is What a Feminist Looks Like” and “Girls Just Want to Have Fun – damental rights.”
