Cool to it's core. Someone or something that seems to have been born under the cool star. Natural and uninhibited coolness - in a good way.

Sort of a jazz meets Buddah meets sexy kind of greatness.

When everything is just right and perfect like it couldn't be anything else.
We went to this restaurant-lounge place the other night. The food was amazing and the music was unbelievable! The whole thing was hefner, man.
