fanny clap 

Where a vagina's lips shut so rapidly that they make a clapping noise. Suggestive that they are big flappy flaps and that a large penis has been withdrawn at some huge speed.

A kind of vaginal sonic boom. You need damn big flaps to make a full fanny clap.

<CLAP!>
Dude: "What da fuck was that, woman!?"
Chick: "Damn muthafucka! You took you damn dick out too fast for me, that was my fanny clap Nigga!"

fannyclanger

Female version of a Cockwomble. A portmanteau of the slang term for the female front-bottom and the popular 70s British children's TV show.

She's such a FannyClanger.
