How to quickly stop a fight

I must remember that!

By the way, if I'm attacked, do you think it would work if I pulled my pants down? That is, would it stop the attacker?

Depends on what kind of attacker...

But on a more serious note, sometimes unexpected and socially awkward responses are effective.

I've read a lot of stories about women who picked up dog poop and successfully defended themselves with it by threatening to smear it on their attackers.

There's probably something to be said for being bigger than the other guy, and then standing your ground and staring him down afterward.

I 've heard of victims of street robbers
acting like frenzied lunatics, screaming n running;
either that or SHOOT THEM.
