Muffler Flap

When your inside a chick and your ball sack covers her butt hole as she farts, causing your ball sack to vibrate acting like a muffler flap.

I hate when my wife uses my ball sack as a muffler flap!

flap scrubbing

Literally, manual female masturbation.
Or figuratively, wasting time, as in goofing off,
fucking off, or the feminine version of jerking off

She's obviously so horny it's interfering with her work. She needs to go home to scrub her flap.
Please take a break from your flap scrubbing and bring me a beer.

Vlogger's flap

A word used by Roman Atwood to describe is chicken flap on his arm near his triceps.
The term is derived from the fact that he is a vlogger with a flap.

He has some serious Vlogger's flap, he could probably fly!
