Actually defined as a member of a despised social class, a commoner, a very in-experienced member of the plebs of ancient roman guards. Also low-born, undisinguished, vulgar, and my personal favourite: vulgar-looking.
That person is as Narim as it gets!
or
Everyone hates that Narim, he doesn't know what he's doing.

Comeon, Narim, refer to rune no. 4!!
