A person who tends to work in an office building. That is if your idea of work includes looking good and writing on msn to the people sitting right next to you work!. Usually employed by nerds to look good and distract people from the computer geeks on the lower floors who do all of the work. A cool persons job title is usually personal secretary (no prizes for guessing why!)
A cool person accidentaly comes across a geek and says 'O my god it is some kind of pygmy!'
