Bullying, also known as peer victimization, is a deliberate and unsolicited action that occurs with the intent of inflicting social, emotional, physical, and/or psychological harm to someone who often is perceived as being less powerful. The act of bullying typically happens repeatedly and is a form of aggression and harassment. It can prevent someone from enjoying a safe, stress-free living, learning, or working environment and can be very traumatic.
The harmful effects of bullying may be exacerbated by the frequency, pervasiveness, and severity of the behavior, as well as the power differential between the perpetrator and the target. Bullying can be physical, verbal, and social. Cyberbullying includes sending negative, harmful, or false content via text messages, email, or online through social media.
