a description of the sagging labia minora. When a woman's inner pussy lips hang or protrude outside of a woman's pussy resembling a trucker's mudflaps. Often associated with age or child birth. Loathed by young men, savored by older men. Cursed by all women and often the leading reason for designer vaginal rejuvination.
Ewe, Dad, did you see the mudflaps on that old stripper? Yeah, Son I did. Mudflaps are great to suck on.

Only pertains to fatasses; when the amount of flab you have overhangs enough to interfere with going to the bathroom and thus makes contact with urine or shit making the flab act like a mudflap behind a truck tire.
EG: Damn thats a big bitch, her mudflap is bouncing off her knees when she walks!
