That’s definitely bullying behaviour. I don’t know exactly what you’re asking. Bullying can range from ignoring or talking behind someone’s back, to physical assault. They are not average experiences, especially being a repeated event, in normal friendships and relationships.

Several actions included in bullying are also criminal offenses, and needs to be taken way more seriously by the adult world - not minimised, labeled “bullying” and nothing more being done about it. If someone physically assaults someone else, there should always be a police report filed because then social services will be informed if the attacker is too young to be criminally responsible. Even if it just words and threats, or stealing or destroying someone else’s items.
