Bullying is an act of repeated aggressive behaviour in order to intentionally hurt another person, physically or mentally. Bullying is characterised by an individual behaving in a certain way to gain power over another person. Behaviours may include name calling, verbal or written abuse, exclusion from activities or social situations, cyber-bullying (which involves use of email, text messages or chat-rooms to humiliate or cause distress), physical abuse and coercion.
