millsie 

The most amazing person anyone will meet in their life. She is funny and by far the smartest person you'll ever meet. She can light up the room with her gorgeous smile and can make anyone else smile at the blink of an eye. She's the sexiest girl you'll ever meet and is a demon in the bedroom. She's drop dead gorgeous and any guy would be lucky to have a millsie.

"Hey look at how gorgeous she is"
"Duh that's millsie"
