Banging her back out 

Stereotypically, HARD, rough sex with a black female that has a big butt. Sex style MUST be DOGGY STYLE, not anal. The butt only comes into play as cushion because you will thrust so hard. The main goal is to get her as loud as possible, whilst providing pleasure for both parties.

Load moans were heard from my room by all because I was banging her back out.
