When one sticks both thumbs up on either side of their face, about a foot away from the ears, awkwardly smiling and saying the words, "cool deal". A lifestyle for some, many have taken it to define the highest state of quality for an action or event.

A member of the "Do what" and "Do what, now?" family, cool deal is often chronically exploited as a filler word. Beware of "cool deal" if adopted by you superiors as it can be highly infectious.
