The unofficial term used for expressing the word 'Cool' in Australia. If something is normally described as being "Cool" in conversation, it now becomes "Coolaroo" if you are in Australia. It is on trend with a national custom to add Roo to the ending of a word.
Ex.1: "What did you think of that new movie Lion with Nicole Kidman?"
"I thought it was Coolaroo!"
Ex.2: "Your table for 4 is ready sir"
"Coolaroo!"
Ex.3: "The dentist will see you now"
"Coolaroo!"
