The combination of the words "shiny new toy", and "new pussy." A person that is fucked for sport, and to maintain one's sexual prowess...not for emotional support, or a long term relationship.
1) "So, why don't you get shiny pussy to take you to the airport?"
2) "This is Heather...my shiny pussy."
3) "Naw, man...I got rid of my old pussy, and replaced her with some shiny pussy."
