The most offensive word in the history of the world, because it can be used to describe anybody (a person does not have to fit an ethinic group, lifestyle, tc.) to be correctly idenified as a coundis. For example, for a person to be a nigger they would generally have to be black.
Christopher: You are the ugliest coundis I have ever met in my entire life!
Leroy: *cowering in embarrassment, shame, and fear* How could you say a thing like that?
