Wasi'chu Wašíču is the Lakota and Dakota word for people of European descent. It expresses the native population's perception of the non-natives' relationship with the land and the native population. The word means "takes the fat," or "greedy person." Typically it refers to white people, but does not specifically mention skin color or race. The term "black wasichu" has been historically used to describe a person of African descent, and a Native American who adopted non-native ways could "make himself over into a wasichu".
