Bullying  

Aggression that is intentional and repeated over time, and there is an imbalance of power between the perpetrator and the victim. Bullying is a specific type of peer victimization that is categorized by these components, which indicate an ongoing relationship between the bully and the victim.

When a bully is overtly aggressive toward a victim (e.g., repeatedly hits, teases, or steals from the victim).

When a bully expresses aggression toward a victim through a third party (e.g., spreads rumors and gossips). Although the bully and the victim do not actually interact with each other in instances of indirect bullying, this aggression still has an impact on the well-being of the victim.
