Having oversized labia that will not be contained by undergarments and thus move freely in a flapping motion.
Dave, your sister's coochie flaps are dragging on the floor and getting all dirty. Doesn't she notice, or is she red facing it again on blackberry brandy?

The busted up labia of the female genitalia, closely resembling the meat of an Arby's roast beef sandwich. Unfortunately they do not go as well with Horsy sauce.
Oh my god!!! What the hell happened to your vag? Was there a terrorist attack on your pussy? Those cunt flaps are so loose you could use them to make a tent.

On windy and even breezy days when a slutty woman's pussy lips can be heard flapping in the wind, giving you the impression there is a flag nearby.
Dude, do you see a flag anywhere around here? I can hear one, but I sure as hell can't see it. Oh wait, nevermind, your mom is wearing a miniskirt with no panties again. That is one flag flapping bitch!

The flappy and saggy skin that hangs from the privates of a woman, but there can be cases in which males have them...are gotten rid of by sag-flap removal surgery or hidden by various methods of tucking.
Felicia went to the grocery store and bent down to pick up a cucumber that had fallen, and next thing you know her sag-flap or huge flap of skin flops out of her shorts... either Felicia didn't have her crap together and tucked and rolled her flaps wrong, or she needs to ditch the daisy dukes.. just saying Felicia you're a sag flap girl, be proud, but not too proud...
