If a woman really wants to hurt someone her target will, I think, depend on the gender of the person she's angry with. If it's a man she'll go for the balls, if it's a woman she'll attack the face. With a man his balls are the essence of his manhood, while women think their face is the most vital part of their appearance, hence making these the obvious targets if the intention is really to hurt and humiliate. That's my theory.
