"I'm a Jazz Baby! Yeah!"

Everybody Charleston! I'm not exactly sure when and where everyone got together and voted on calling the twenties "Roaring", but it seems to have been nearly unanimous. And "roaring" is a pretty eccentric adjective for an era, now that I think about it. Do you describe anything else as roaring, I mean anything you wouldn't find in a zoo? As to our own day and age, need I point out nobody has even figured out what to call the damn decade in the first place?
