When a female uses a vibrator so powerful it causes the vaginal lips to slap each other causing the lips to make a "fart" sound.
Sarah: hey Jen did you use the penetrator 6000 last night?
Jen: yeah it literally caused me to fart flap it was hilarious.
Sarah: oh Jen you love abit of fart flapping.

Female of Fomunda Cheese. Crud that collects/grows between the flaps of the vagina when it has not been washed. This can consist of Sweat, Dirt, Discharge, and possible semen...god knows what else gets stuck in between there.

I could hear my roommate whipping the flaps last night after going to bed.
I walked in on my sister whipping the flaps to lesbian porn.
I spent the whole weekend whipping the flaps after my boyfriend canceled his visit.

The labia of a promiscuous woman. Can also be used to generally describe skanky, undesirable pussy-lips.
"Man, I went out with this girl last night, and she had a pair of bastard flaps on her."
"I hate it when a girl forgets to clean her bastard flaps"
