A slang term combining ninja and injun, used to describe Native Americans depicted as having superhuman fighting skills. The term is generally applied to popular film depictions of Native American combat prowess, such as "Brotherhood of the Wolf," and seems to have begun with "Last of the Mohicans."
Dude, that ninjun totally did a backflip onto that dude's head and then threw a tomahawk into his partner's face, then he did a spin kick and knocked the sheriff off the side of a cliff!
