Bullying can mean someone is hurting you physically, like pushing you around, or hitting you. It could mean that they are threatening to hurt you.
It can also mean they say mean things to you such as call you names, or spread lies about you.
If this happened once and it was with a friend, and they said sorry, or you sorted it out, we probably wouldn't call this bullying. But if it is something that happens a lot, like many times a week or if the one person does it to you every time they see you, that is bullying.
Many people who bully are not very happy people themselves and that is why they like to make other's feel bad. They might be going through their own problems that you don't know about.
