Jonathan Green (Mister Slang) said in a recent podcast interview (http://slate.me/1tyUHIO) that slang is from the male perspective. Men have historically ruled the public sphere, so the shaming slang comes from them and shows their biases about the place of men and women in society.
Men do things and it's cool and normal. Women do the same thing and they're not good, not worthy, not allowed to participate in society. Men doing "women" things are also bad, maybe worse.
For a male equivalent, see the affectionate common use of wifebeater shirts.
