This article explores the centrality of victims' testimonies in the moral enterprise or phenomenon of bullying as a form of diffuse violence in the Brazilian context, based on a specific group of histories: those in which adults reorder their reporting of juvenile memories of aggression through this concept. The study demonstrates how a knowledge of psycho-sciences is framed within such testimonies, not directly, but mediated by the mass communications media that currently pulverize declarations of this type. Massive adherence to this construct has produced a series of ethical and political repercussions that are discussed in the article.
