Mud Flap

An empty scrotum or ball sack.

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.

Mud flaps

When an ass receives so much Intercourse that it becomes loose and resembles a loose vagina. Similar to meat curtains.

My asshole is so loose that I now have mud flaps.
