A female wearing no underpants or cover for vaginal and anal area. "Flap" meaning part of clitoris. Like "Free Ball" for men.
I love Free Flapping in the summer, because my pussy sweats.

Get the Free Flap mug.
When a woman goes out without underwear. The female equivalent of free balling.
Trish ain't got no panties on. She free flapping!

To not wear any underwear. The female equivalent of freeballing.
"I am not wearing any underwear today, I'm freeballing".
"Oh, so you are free-flapping?"
"Being a female, I suppose I am!"
