|I don't know what this means.|
My best guess is that it's a play on words between "cool" and "hottie", but none of the definitions of either word make sense. Aren't flowers suppose to heat up a romance and not cool it off? I could see flowers cooling off a hotheaded person, maybe? Is the hottie too cool for school and is in danger of flunking out?
All I know is that a rose by any other name wouldn't be as cool.
