Yes, there is what the police know as verbal judo. There is a lot of cussing involved with teaching it. Essentially, when a bad guy is coming at you, he thinks you are the victim and victims typically lie down and take it. That's how the bad guy chose you to begin with because you look like an easy target. Sometimes there may be a small woman that may be walking around minding her own business and this guy comes and attempts to grab her, she can back away and scream at the top of her lungs. Literally she would yell, back off or I will tear your throat out and I will gouge your eyes!" I mean just really make a ruckus, make that guy stand back and think "wow, she didn't look like that a minute ago!" So, verbal judo is kind of a way to control the situation. When we are talking about a woman being attacked, the screaming, the interruption of the brain pattern helps distract the guy who was determined he was going to get her. Now all of a sudden, she is putting up a fight. So, you may very well be able to deter them by using a type of verbal judo in defense. But again, sometimes guys aren't deterred by that and they continue to attack and then you are going to need to know where your pepper spray or stun gun is.
