"Bullying doesn't always happen to a single individual. If it's a group, it's usually a significantly small group. Maybe two or three people at the hands of another larger group or higher authority. There is typically an upside to the bully which gives them the upper hand once the bullying begins. Their upper hand denotes a presence of power or dominance. That's the core concept of bullying- an imbalance of perceived power. Sometimes that power is revealed by a ton of different reasons, but other times it can be delegated to a person with an authoritative position."
