How do you call a woman stupid without her thinking it's a compliment?

Just some women of course. The mainstream ones that subscribe to Disney stars. Everytime my sisters are back from school, they'll start exchanging 'stupid blonde' jokes etc. You'll want them to shut their stupid mouths up but unfortunately it gets worse because according to Disney, popular girls are loud and stupid. You want to break their annoying skull but who knows if you'll catch the horrible locker room smell. Feminists, where are you? You can't see this happening then promising girls a 'fair and equal'(affirmative action) education in college.
