Why are women more vituperative and have a vicious tongue?

Whenever an argument breaks out and women are involved then in majority of cases it is the women who excel in tongue lashing administration. If it is a man to whom it is directed to then he gets so enraged that he cannot match her with words but has to use his physical strength to stifle her.And if is a woman, she will have some choicest abuses ready or have a counter argument to make the other wince. When we see some such quarrel breaking out in some places where women gather to fetch water from a common tap, men cannot stand there. In the home front, when such a quarrel breaks out between two ladies, men dread to intervene.
