Blow your back out 

To fuck someone so good, they can't walk for a couple of days. Hence their back is blown out.

Boy: Damn, girl, I can blow your back out
Girl: Um, I don't think so, I have a soccer game in the morning and I'd actually like to walk.

Doggie style vaginal or anal sex that is deep and vigorous leaving the recipient clapped up good with some rearranged lower intestines.

My asshole is ripped from stem to stern after that random last night decided to blow the back out on me.
