CINCINNATI (TDB) -- Mankind seems to have been wired with a never-ending itch to explore and discover new ways to denigrate other people and cultures. Now we have the word "Canadian," which reportedly is becoming freighted with a slang, mean street definition. It is now being used to describe blacks and is a substitute, or coded, racial slur to replace the N-word. A report of this troubling linguistic shift comes via CincyBlurg, who said a friend had noticed that white people were calling her Canadian.
