Mud-flappin'

The act of not wearing underwear, for females. Just as mud flaps behind the wheels of a truck flail wildly in the wind, a saggy vagina may mimic this flapping motion without the restriction of underwear. This is the alternative to "free balling" meant for female use only.

"Dude, it's my laundry day, so I'm mud-flappin' it today."

Floppies

1. A group of teenage girls who try to be popular (ie poppies) but fail
2. A group of teenage girls who erroneously think that everyone wants to be them
3. People who name their group and/or put the members of said group in number order

Every time the floppies post matching Facebook statuses, I slit my wrists.
