Indifferently what there is people opinion on this forum, women in real fight scratch. You can see this often. This is obvious. They scratch rival face and body. Long nails are they natural weapon. Unfortunately scratching leaves the traces which have to be heal. Pretty appearance is very important for women except this. That is why women know that, hurting and marring rival's face during the fight is the good punishment. Scratching belongs to women fight so as hitting, smacks in face, hairpulling and different "techniques". If I like catfight then scratching is OK.
Titfight is the kind...version of scratching. If woman get the access to rival breast, then she squeeze, pinch and scratch them too. In real fight this happens very infrequently, but I saw this in several fights on Youtube.com. They squeeze and scratch breast, pinch nipples through clothes more often. Particularly if this is the T-shirt or bra. But this is already different subject.
