Get informed : Bullying

Bullying is the repeated use of power or force to hurt or bother someone. It is thus based on an imbalance of power.

Teasing or bullying.
Having fun by teasing friends in a friendly manner isn’t bullying. On
the other hand, even apparently harmless behaviour can turn into
bullying if it is done often enough and with the intention of hurting.

Straight to the heart. Like all forms of violence, bullying is serious and may have many consequences — for victims, aggressors, and witnesses.
