It's all about things that are iconically (or humorously) feminine, just like the male counterpart. So while you may get a man card for growing an incredible beard, a woman could get points on her woman card for learning to walk very gracefully in heels.
A man could get major points for building a house, and a woman gets tons of points for giving birth.
Also, I know PLENTY of women who love chick flicks, are shopaholics, and could probably do a triathlon in 4 inch stiletto heels. Just because the majority of the women HERE don't do or enjoy those things doesn't mean that the "woman card" is that unrealistic.
To prove my point, I'll throw in some stuff that Could earn me points on MY woman card:
I can cook
I have sewn my own clothes before, and yes they were perfectly presentable.
Though I don't prefer walking in heels, I can walk very gracefully in them when I do wear them.
I enjoy wearing skirts and dresses. In fact I wear them 95% of the time
and back to the OP. Things that could get my woman-card revoked:
i despise shopping for clothes/accessories. I despise it with a fiery burning passion.
I rate the majority of chick flicks as awful.
I have never had a professional pedicure.
