Cat

In the 1970's Cat was used to describe a person that was hip or cool. They dressed in berets. Most of their clothing was black and white. They hung out in coffee shops. Liked to stand up in front of a Mic and read poetry. They had an aura of being really smart and really mellow.

"Look at that guy over there wearing the beret and reading poetry. He's a really cool cat. "

"Hey cats, wanna come hang with me at the coffee shop?"
