Boys and girls both seethe and gossip, experience betrayal and rejection. Boys usually don't challenge the social hierarchy like girls do, says Rosalind Wiseman, Parenting Educator.
When boys feud, their social rankings usually get reinforced in the end. After the fight, the boys go back to what was before. Girls, on the other hand, take out their anger ( or insecurity) by morphing the make up of their friend groups. This form of fighting--in which the goal is to harm the other person's "social status" and relationships is called relational aggression.
This process can last for weeks or months and almost always involve manipulation of some sort and some form of exclusion (Lisa Freedman, Real Simple March, 2015).
