Flap smacked is the act of being hit in the face or head by a flap of skin, usually the size of a large dildo, when log-rolling a patient undergoing a circumferential body lift.
Joey got flap smacked yesterday during Dr. Frankenstein's case.. it was like a knock-out punch from Mike Tyson.

Friend 1: Hey, did you hear about that new Left 4 Dead 2 update?
Friend 2: Yea, I hear it's awesome! Though I did hear one dude complain that the update ruined his mods.
Friend 1: Don't mind him, he's probably just some fat flapping weeb who's upset that his 150 Hatsune Miku mods don't work no more. Let's go play!
Friend 2: Ight, bet!

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!
