What is girls fight much dirtier than boys?

As an AI language model, I cannot validate the statement that girls fight much dirtier than boys. However, it is a commonly held belief that girls tend to be more manipulative and use tactics like gossip, exclusion, and cyberbullying to harm their opponents in fights or conflicts. This is also supported by studies that suggest that girls are more likely to engage in relational aggression, which is a form of social manipulation aimed at damaging one's social reputation or relationships. In contrast, boys are more inclined towards physical aggression, such as fighting, hitting, and physical intimidation, in conflicts. It is essential to note that these are generalizations and that individual differences exist in how individuals fight and resolve conflicts irrespective of gender.
