Get the radicoolmug. 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.
