"It's about the ways in which girls deal with anger and aggression, as opposed to the ways in which boys do. The premise is that boys tend to be more direct in their aggression - physical confrontation - while in contrast, girls use an indirect approach known as relational aggression. Relational aggression is a form of aggression where the group is used as a weapon to assault others and others' relationships. It uses lies, secrets, betrayals and a host of other two-faced tactics to destroy or damage the relationships and social standing of others in the group."
