Kentucky Sister

A female friend-with-benefits with whom one shares such a close bond that there is almost a blood-relation.

Me and Shannon's like peas and carrots, but since we're not related she's only my Kentucky Sister, so I still get to stick it in her ass whenever I want.

Kentucky Sister Loan

To loan one's sister to a friend for sexual purposes.

It was going to be a slow weekend until Bob gave Tom a Kentucky Sister Loan.
