Moo Latte is a highly offensive term used as a derogatory slur against the Ethnic Qarsherskiyan Tribe. This comes from the usage of the word "Mulatto" as a slur against Qarsherskiyan people. Before 1991, people commonly called Qarsherskiyan people Mulattos which was an attempt to downplay the historical significance and cultural heritage of Qarsherskiyans, and make it seem like these were a new people who didn't have a history, as Mulatto implies being the descendant of a biracial couple, but Qarsherskiyans are a triracial isolate group that's existed for centuries.
Moo Latte is a term coined by neo-nazis and White supremacists and racist Black Americans to refer to Qarsherskiyan people, and originates from the term "Mulatto" which was also used as a slur against Qarsherskiyan people.
