Abstract
This work tries to broaden the discussion about school bullying and violence. In the first place we will define both terms and their characteristics, paying particular attention to bullying, which we will define as peer abuse (maltrato entre pares, MEP). Later, we will describe the bullying actors and their interchangeable roles, as well as its present and future consequences. Finally, we note the complexity of the abuse origin, intimidation or violence, which goes beyond the school boundaries and places us among psychodynamic motivations and vicarious learning.
