Cyberbullying usually includes a bully (or bullies), a target and several observers. Cyberbully is someone who engages in cyberbullying. Cyberbullies use the internet and electronic devices to emotionally hurt others by making fun of them or insulting them.
Targets of cyberbullying are individuals who are hurt by such actions. Most often, cyberbullying does not stay limited to the bully and the target. There may be many observers, who can take on many roles: they can be passive bystanders, they can perpetuate the bullying or they can act to stop cyberbullying.
