There is cool, there is wicked, and then there is WICKED COOL. Best to be used when something is very 'fly' and/or 'hip' but radical seems to hippy, dope seems to east-side, and phenominal seems to intense to describe the coolness of the situation/action/object.
"Yo, hommie, your tripple backflip of the high-dive was wicked cool"
"Wear some wicked cool bling for the ching ching"
"Tonight is going to be wicked cool... are you ready to giver?"
