Slang, it’s defined as language peculiar to a particular group, composed of arbitrarily changed words and extravagant figures of speech. That sounds about right. It’s also a way we define ourselves and our generations. And it can make for a lively conversation. My daughter Sydney, a Gen Z, my wife Sara, a Gen X and I, just barely a Boomer, sat down and talked slang. From C.E.O. and MAIN CHARACTER to GRODY and PHAT. You’ll get an education, I sure did.
