black'd out 

When a drunk chick gets every hole/orifice penetrated/gaped by a group of black guys.

Jenny got so blacked out at the party, and by the end of the night she was getting black'd out by those black gangstas.

I'd knock the back out of that! 

Said about a sexually appealing woman, with whom you would be very eager to have sex.

To explain the metaphor: you may be a little too vigorous, and push your penis all the way through her, hence, knocking the back out of her... Obviously not physically possible, but a good, although rather crude, metaphor

Guy A: Phwoar, Check her out, what a stunner!
Guy B: God yeah, I'd knock the back out of that!
