Juss flappin' yer coat-tails

In other words, juss sassin' ya. Comes from da playful-but-annoying practice of coming up behind someone who's wearing a long jacket with a divided lower back, grabbing da jacket just above da slit, and then vigorously/rapidly yanking da lower part of da jacket in and out to make da pair of tails slap against da person's butt.

Me: If yer too warm, why doncha go take a dip in da ocean?
You: Jump in da ocean??? Are you crazy??? It's chilly and whitecaps-windy out there!
Me: I know, I know... juss flappin' yer coat-tails...! :D

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'.

Mud-Flappin'

When you are having anal sex with a girl and you pull out and put it into her vagina.

Friend #1: I was have amazing anal sex with that filthy little filly Stacy and I pulled it out and put it deep in her bum, straight mud-flappin' bro.

Friend #2: Amazing, pure class.
