What IS Bullying?

Okay, this seems like the beginning of a meaningless post, but I PROMISE it isn't!

So What Is Bullying?
Bullying is considered a crime in some places, I personally agree and think it should be made an offence in every country. :) 
You see, bullying is not only a physical assault, it can verbal, it can be written, it could be anything. The definition of bullying is to: 'Use superior strength or influence to intimidate someone...' This superior strength could be height, popularity, it could even be riches; but as long as it is used to harass others and cause them emotional distress, it IS bullying. It's not just a one time thing either, it's repeatedly, over and over again for weeks, months, years.
Is There Only One Bully If It's A Group?
No there doesn't have to be only one bully. If... Let's say x is a bully, and x bullies y... But x has a large group of friends who surround him/her and cheer him/her on but do not say/do anything directly to the victim; would they still be classed as bullies? Well in my opinion yes. You are standing there edging someone on, you aren't telling them to stop, you are encouraging them. And therefore I would class that as bullying. Do You agree?

Um, So That's It Really... :D Any Questions? Just Leave Questions In The Comments :)
