Jamma Slamma

The opposite of the traditional "slamma jamma", aka. sex. You flip your partner around in any direction you choose, without pulling out, and continue giving it to them. Instead of being slamma jammed, your partner now gets jamma slammed!

Adam: I was slamma jamming that girl last night, but she kept talking about Scientology.

Paul: What did you do about it?

Adam: I flipped her over, and started Jamma Slamming her! It felt great.

Diddy: Did she stop talking about Scientology?

Adam: Yea! Jamma Slamma is awesome.

Sean: I need to try this sometime.
