A Shart Flap is a piece of absorbent material, like bamboo cloth, sewn into the back of Commando brand shorts to prevent visibility of any shart aftermath.
Thank God my Commando shorts had a shart flap or people could see my Taco Bell accident that snuck up on me.

Booty flap is when a girl flaps there booty so hard that whoever watches it, gets a little funky when they watch it.

When you go down on a lass, spread her legs to open the heavenly gates, as you go down on her you do a loud burp right between the flaps. ( excessive amounts of either alcohol or gas-inducing drinks help with vibrations)
(Dan) Do you remember that 'Shiela' from the bar last night Shane?
(Shane) yeah the one with the fat arse?
(Dan) yeah mate that's the one, well I took her home and after all that beer.......I had to give her the good ol' flap burp!

When your mouth overides your ass. Talking way way to much about nothing. Not being able to stop talking.
