Bullying is when someone picks on you, mentaly emotional, of physical. It can be in many different forms, like beating you up or spreading rumors. I've seen people being teased about being different, in weight, color, religeon, lots of things. If you are a victim of bullying, you should stand up for youself (be sure you don't become a bully yourself) and if the bullying dosn't stop, tell an adult. To stop bullying, you should stand up for the victims, even if you don't know them.
