A girl that means the world to you. She's damn fine and gorgeous to all. She's a girl you wouldn't typically date because she's a freak in the sheets. However if you find yourself dating one of these unicorns known As kitten baby you better hold on tight because you're in the ride of your life in so many different ways!
