In this paper we will analyze the thinking of the French philosopher René Girard about the mimetic desire that is produced in society and its derivation towards the mechanism of scapegoat. This thinker starts from the fact that we all move through this mimicry and that it can be mobilized until it reaches violence, removing and annihilating the person or group considered as guilty. As an example, two cases of social violence occurred in Korea: first, the woman who refused to clean her dog’s excrement in the subway, known as “the dog poop girl”, and second, another young woman who commented on a television show that short men were losers, and was named “loser girl”.
