A little re-invention from O.O as being weirded out or scared...CO.OL is something you say when a person is like, telling you something creepy or weird, but you have that sense in you that makes you reply with a "cool". Why not combine? Hmm.
person1:my cat scratched me in the b0oOb 3 times!
person1: yeah i know!
The word "cool" is a word of far superior quality than the word "awesome." The word "awesome" is connotated most frequently with bum pirates, drug-riddled shoplifters, or other people of generally poor caliber, whereas the word "cool" connotates a standard of being far exceeding all other words. "Cool" has been used throughout time and space and will continue to be the supreme king of all that is admirable, great, or majestic. "Awesome" forever will be a subset of the word "cool", but "cool" is without a doubt the indisputed champion, godfather, and ultimate, complete, freakishly perfect winner of all other words... especially "awesome."
Hey, want to jump out of a plane in a kayak and land in the middle of a class V rapids while wearing a Superman costume?" "Sure! That would be COOL!
