Mudflappin'

The act of a female "going commando." It can get pretty messy down there, so it is up to the labium majora and labium minora to flap around freely and fight off any kind of dirt or grime.

Jon: "Hey Sally, wanna do the dirty?"

Sally: (removes pants) "What kind of dirty?"

Jon: "Eww God. It looks like you rubbed oatmeal all over your vagina!"

Sally: "I wouldn't doubt it... I have been mudflappin' all week"

Jon: "Now I see why they call it the dirty, baby."

Mud Flapping

Mud Flapping is when a guy challenges or questions another guy’s manhood based on the former not being capable of a feat that he himself has just proved himself unable to accomplish

Example:

MudFlapper: “Hey bro, you got a knife I could borrow?”
RealMan: “Sorry bro, I don’t have it on me.”
MF: “What?! A real man always carries a knife!”
RM: “YOU don’t have a knife idiot. Stop all your mud flapping and get out off my property.
