¿That bullying is?

 It is a Dutch word proviente meaning of the word harassment.
The first used the term "bulliing" within the meaning of bullying in their research was Dan Olweus, who introduced in the '70s in Sweden a long-term study that would culminate in a comprehensive anti-bullying program for Norwegian schools.
Formerly this word was not mentioned, but due to the alarming increase in cases of persecution and attacks that are being detected in schools, which leads many students to live truly terrifying situations, it is now is talking about it anymore.
Bullying is present in almost anywhere, is not exclusive to any sector of the society or about sex, although the profile of the offender himself is seen predominantly in males. No differences exist with respect to the victims.
The attacker harasses the victim when alone, in bathrooms, hallways, in the dining on the patio. For this reason, teachers often are not aware of.
But this is not a simple push or comment, it is a situation
that if not stopped in time can cause severe emotional harm to the victim.
