Weird self-defense myths for women

This was prompted by being asked by a friend to stay on the phone with her while she walked to the station. I gladly did so (to be polite), but... Well, if she thinks this made her safer in any way, she's just wrong. XD I've taken this occasion to compile the weirdest, most useless, and in some cases even counterproductive advices I've ever received about "self-defense for women".

( Weirdness! )

That being said... Self-defense is a good thing.
