As a teacher, I would say that I disagree with Mercedes as to the extent of behavior being bullying. Bullying is part of repetetive pattern, but not necessarily in regards to one victim. Many bullies bully whoever happens to be convienent, so it is possible each victim could be victimised once. The act, being part of a pattern, can be accurately labeled bullying.

However, the key is that billies target weaker opponents. Bullies never pick a fight unless they're certain the odds are in their favor. If you stand up to a bully, win or lose, they back off: you are not worth the trouble. Trading barbs between equals is not bullying.
