A fusion of Radical and Cool. Not to be used unless somthing is of the upmost awesomeness, when neither rad nor cool can describe such (insert noun here) to its fullest sense. Nothing can be sorta Radicool, the only word that shall be used before Radicool is Totally. The word shall always be respected and used properly. If used improperly, you have permission to roundhouse the violator. 1 kick per violation.

Synonyms: Fully gnarly, massively sick, incredibly wicked, hypnotically phycadellic, ect.

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.
