Hello,
Bullying consists in repeated attacks on the same person by a bully or a group of bullies. Bullying doesn't necessarily mean violent behaviour or physical assault. There are three main forms of bullying :
Physical bullying : beating up, hitting, kicking, slapping
Verbal Bullying : insulting, taunting, threatening, sneering at
Psychological bullying : ignoring, excluding, spreading rumours
With new technologies (mobiles, internet, snapshat, social networks...) new forms of bullying have appeared : they are called cyber-bullying.
Good Luck.
