The words now associated with female aggressive behavior include: excluding, ignoring, teasing, gossiping, secrets, backstabbing, rumor spreading and hostile body language (i.e., eye-rolling and smirking). Most damaging is turning the victim into a social "undesirable". The behavior and associated anger is hidden, often wrapped in a package seen as somewhat harmless or just a "girl thing". The covert nature of the aggression leaves the victim with no forum to refute the accusations and, in fact, attempts to defend oneself leads to an escalation of the aggression. via Bullying in the Female World | Psychology Today.
