Uchihacism 

1) The discrimination of one or more members of the infamous Uchiha Clan of the Naruto anime/manga series by Masashi Kishimoto. Mostly practiced by first generation inhabitants of the Village Hidden in the Leaves. Still, examples of Uchihacism have been displayed by current-day villagers and Naruto fans alike.

2) "Uchihacism," discrimination based upon hatred towards one particular family, the Uchiha Clan, may have been the catalyst that ultimately ended the Uchiha Clan's existence. The notoriously known Uchiha Massacre was led by two individuals both members of said clan, Itachi Uchiha and Madara Uchiha. Only two known survivors of the Uchiha Clan Massacre currently fictionally exist, Sasuke Uchiha and Madara Uchiha.

3) One who practices Uchihacism is considered an "Uchihacist."
