As you may know, I'm always interested in expanding my vocabulary, so when I hear a new word, or an old word used in a new context, it tends to get stuck in my head. And like a crummy pop song, the only way to get it out of my head is to put it into yours. You've read Billy Bob's sex advice, right? Now I want you to go out and use "swarthy" in a sentence five times today, but here's the trick: try not to use it as a tired-ass racist cliche, okay?
Good luck.
