look up any word, like plopping:
The sexual part located in the pubic region of a person with no penis or vagina, and is the main ingredient in the popular meat product known as the Slim Jim. It is a flap of skin that appears to be an external, dry vagina. The Skingina has been found to be completely useless in the human body so has been cut off of its wearers and used by the makers of Slim Jims.
Guy 1: What is this shit in my Slim Jim?
Guy 2: Oh that? That's just a piece of Skingina.

All of the Jonas Brothers have skinginas.
