Flap Smacked

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.

Under flap

The crusty film that forms made of sweat that collects under a breast, usually a large breasted girl, or woman.. or anyone who has breasts large or saggy enough to cause and form pockets, if its large enough to hide items, its large enough to collect dirt sweat lint and small creatures. Liken it to swamp ass or belly button lint..

Dude, she flashed us and under flap fell out.

Much to his surprise and horror when he got done licking there, there was some under flap stuck in his teeth

Horseshoe flap

The horseshoe shaped flap of skin between really big tits that cause the skin to pull downward in a horseshoe shape - young or old

I totally hooked up with a chick that had the horseshoe flap between her tits.
