I'm pretty sure you don't need one. But ah, what the hell.

Usually an insault in which a woman is being called a slut or a whore, but has recently been taken in a completly different direction by many youngsters of today, it is now commonly used as a synonim for good. Depending on the context is wether or not its an insault or a compliment.
For num. 1 "God, Jill's slept with every guy at this school but me, shes such a slut muffin."

For num. 2 "Woah, Rachel your looking pretty slut muffin today."
