Where a fat guy doesnt have a stomach hanging in front of him like a beer belly or a keg its a big piece of skin hanging down to his waist or his knee's. Like the flaps on the back of the truck
You anda friend see a guy who streaches and lifts his shirt and all you see is skin not even shaped hanging down.
Your Friends says "Ew he doesnt even have a keg"
You say "No joke it looks like a Mud Flap hanging down like the back of a truck.

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.

Balls. When sitting correctly, a mans testes may cover the anus and becoming a 'mud flap'. Also, when two are engaged in intercourse in the missionary position, the mans testes may cover the woman's anus and therefore becoming the woman's 'mud flap'.
