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."

Stink Mud

Typically a type of shit you would be taking if you had just got done drinking all night and eating Mexican food. Be careful of suspicious gas and stomach aches, the stink mud can really sneak up on you.

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

mud dropping

To excrete fecal matter while standing up.

I couldn't find a toilet in time, so I did some mud dropping on the way home last night.
