The combination of the words "radical" and "cool", as used by the Schultz girls. It does not replace "radical" and "cool", it only better describes something that is over-radical and over-cool. The word is used only occasionally to show utmost approval of something, and should not be perverted with overuse.
Man, its so hard to get a job with that company. That's radicool.
