Mud-flappin'

The act of not wearing underwear, for females. Just as mud flaps behind the wheels of a truck flail wildly in the wind, a saggy vagina may mimic this flapping motion without the restriction of underwear. This is the alternative to "free balling" meant for female use only.

"Dude, it's my laundry day, so I'm mud-flappin' it today."

drilling mud

The sticky stuff left on a penis after anal intercourse. Especially notorious is the "hot drilling mud", which comes if the recipient had spicy curry or other spicy food earlier.

Comes in heavy and light varieties, depending on diet.

Similar to santorum, but thicker and less frothy.

You should have had an enema, now I'm covered in drilling mud.

Man I'm about to go return some stink mud to the earth mother
