Other than that long chat you used to have with your boss, just in case he’d been thinking about giving you a raise, but wasn’t because he felt you were earning far too much money already, “parlay” means this silly — and apparently (for its day) — risqué song from World War I. It’s about the young ladies of France, but really … it’s about wanting to go home.
Come to think about it, isn’t that what most war songs are really about? When all is said and done … beat them up, then let’s go home, please.
World War I was the longest war, the ugliest war, and we are still fighting its battles today. We give the old battles new names, but they are the same, old battles.
