When did the words "like a girl" become an insult?

That's exactly what Always asks in their "Rewrite the Rules" campaign, perfect for your Friday night fix of girl-power.

In the video, two groups of people are asked what it looks like to run, throw and fight "like a girl": older men and women, and young girls. The former do silly body gestures and flail their arms, while the young girls leave all that out, with one girl saying running like a girl means doing so "as fast as you can."

“I think it definitely drops their self confidence, and really puts them down, because during that time they’re already trying to figure themselves out,” one of the older girls Erin says after the experiment. “It’s kind of like telling them that they’re weak, and they’re not as good as them.”

Take a look for yourself... like a girl.
