Bullying is the use of force, coercion, hurtful teasing or threat, to abuse, aggressively dominate or intimidate. The behavior is often repeated and habitual. One essential prerequisite is the perception of an imbalance of physical or social power. This imbalance distinguishes bullying from conflict. Bullying is a subcategory of aggressive behavior characterized by hostile intent, imbalance of power and repetition over a period of time.

Intimidation is a behaviour and legal wrong which usually involves deterring or coercing an individual by threat of violence. It is in various jurisdictions a crime and a civil wrong (tort). Intimidation is similar to menacing, coercion, terrorizing and assault in the traditional sense.
