mud flaps

The human buttocks; specifically, the skin and muscle enclosing the anus. The body part that sandwiches residual fecal matter attached to the rectum, thus providing a buffer between one's undergarments.

My mud flaps felt like sandpaper, leading me to believe that I may not have adequately wiped myself.

When she waves, her mud flaps just keep on swingin' in the breeze.

Pat was born without balls but still has a sack dangling; when he's getting pounded from behind, it acts as a mud flap to keep shit from getting all over the place.
