Mr. Flapper

A very loose vagina (or vagina lips). And when anal fucked, the vagina lips flap with every thrust.

I like to call my pussy Mr. Flapper

wank flapper

Someone with terrible opinions who just won't shut up about them.

Elon Musk is such a wank flapper. He's posting a bunch of tweets about how corporations are people and unions are bad again.

flapper schmeat

Flapper schmeat is the outer lips of a vagina that are so unbelievably used that they jiggle when she walks, commonly smells like the heat coming from the back of a ps4.

And no, don’t mistake them for an outtie vagina. Because Flapper schmeats are the dirty discharge caked skin flaps that are usually so filthy they have turned brown.

If you’re a dirty crackwhore, i’m sure you have some schmeats yourself.

Girl 1: Ugh i can’t believe ayden cheated on me
Girl 2: Omg with who?
Girl 1: With MYA!! she probably has flapper schmeats
Girl 2: Eww!

stivotting flapper

A snow skier who lacks control of his skis and exercises a series of ever accelerating sliding turns with flapping clothes and skis. You must beware for danger of being hit.

As I was skiing out at Whistler I was almost slayed by a "stivotting flapper."
