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
