Trouser-Flappin'

When you are standing next to a speaker at a concert or a party and the power of the music makes your trousers move.

Happens more with bass bins. Coined by DJ Nark.

The music was trouser-flappin' last night! Whopper tunes!

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."

lip flappin'

When you've just told someone something they don't appreciate (e.g. insulted them, their family, or anything else in general) and they're getting all exasperated, and are trying to think of something to yell at you, but their brains aren't as quick as their mouth, so their lips start moving around just gettin' ready for the words with their facial expression still shocked.

So, I called her a dumbass, and I was doing really well at keeping my laughter in check, until she started lip flappin'.
