when something is cool, and something else is really cool and comes along to join it. or instead of saying "thats double cool, or cool x2" etc you should say dualcool.
"wow that guy looks cool"
"hey theres another cool-looking guy"
"and they're meeting together"
"omg thats double cool"
"i think you mean dualcool"

OR

"that really cool actor in that movie is dating that really cool singer"
"thats dualcool"
