Long before the uncool could quietly search for the meaning of baffling slang on Urban Dictionary, they could pay 25 cents for a booklet that promised to teach the “hep” dialect of youth. Hepcats Jive Talk Dictionary, published in 1945 at the height of the swing and jive eras, defined slang largely created in and by Black communities for wannabe hep gees. Here are a few swellelegant words and phrases from the dictionary, some of which are still around—and some of which have fallen out of fashion. (If you plan to click through the dictionary itself, be aware that it contains slang for words and phrases now considered slurs.)
