The term bullying refers to a persistent behavioural pattern of hurting or humiliating others, either through physical abuse, verbal abuse or social manipulation. The bully will often have an advantage over a victim (e.g. greater strength or size or a position of authority), and will often have a more favorable attitude toward aggression. Victims of bullying can be lacking in assertiveness skills, and not know how to defend themselves, or have the courage to do so.
