Cases in point: Arthur Conan Doyle, Conan O'brien, and of course, the legendary Conan "the barbarian" of Cimmeria.

Used as an adjective or noun to describe something as excessively cool or to describe a person who is in complete control of their comic functions at all times. Usually in conjunction with an other adjective.
