smokin skins 

The act of screwing large numbers of sluts in a short period of time.

I was definately smoking skins last weekend.

Smoking skins 

The act of sex, be it manual, vaginal or anal without lubricant when lubricant is needed, making both parties raw and most likely resulting in pain.

I hit this hottie in the elevator, but we started smoking skins so I had to stop until we got some lube.
