As much as I despise William Safire's political view, he does know a thing or two about the English language, so I eagerly await his "On Language" column each Sunday in the Times Magazine. This week's topic was "Kiduage," or the newest slang words and expressions, and it made me feel very, very old. Do you know any of these words: crunk, whip, janky, floss, mack, cheddar? Me, neither. Sigh.
