Having sex with an obese women from behind and your thighs are slamming up against those to big ole butt cheeks
I picked up a full figured lady last night and bent her over and gave her a ham slam

The ham slam is a premeditated act. You must place a ham steak (thick, flexible and boneless) between the matress and box spring prior to any sex act taking place. Have sex in the doggy style position and when the man is about to come, he removes the ham without the woman knowing. He comes on the ham and when his partner turns around to see what he is doing, he slaps her in the face with the come soaked ham.
Warning: The ham slam may cause divorce, seperation or break-up.
