A 50s-styled slang word meaning "Cool." The cat's pajama's, the bee's nee's, and other corny sayings of the like are all synonymous to the "Jads." It's a simpler and more fun way of calling something cool.
Example 1: Boy: Well, Sally Jo, i'm just gonna' go ahead and say it! Well, I think you're the jads and i'd like to take you to the sock-hop!
Example 2: Girl: Wow, Kathy, those tube socks are the jads!
