Freeflapping

The female equivalent of freeballing. Wearing no underwear.

James: Did you get your underwear off of my floor before you left?

Amy: No, I couldn't find them, so I'm freeflapping.

Freeflap

When girls wear boxers/shorts/pants/skirt with no underwear beneath them. It's the same as when a guy freeballs.

Aaron - "Damn gurl! I want seafood. Where's that fish coming from?!"
Sally - "Oh, I'm freeflapping."
