School bullying, like bullying outside the school context, refers to one or more perpetrators who have greater physical or social power than their victim and act aggressively toward their victim by verbal or physical means. This behavior is not a one-off episode; it must be repetitive and habitual to be considered bullying. Students who are LGBT, have parents of lower educational levels, are thought to be provocative, are perceived to be vulnerable, or are atypical or considered outsiders are at higher risk of being victimized by bullies. Baron (1977) defined such "aggressive behaviour as behaviour that is directed towards the goal of harming or injuring another living being who is motivated to avoid such treatment".
