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!

Flaps' eye

The term Flaps' eye came about in the UK in May 2013 as a female version of the male 'Jap's Eye' japs eye or 'urinary meatus', however due to the overly complicated nature of the female genitalia, (and man's inability to comprehend this) there is another hole down there that it can refer to, the vagina.

Urethra:
Anita Dick - Phil I think I've got another UTI again, my Flaps' eye is stinging like TCP...

Vagina:
Phillip McAvity - Mike you'll never guess what I saw this morning..
Michael Hock - What's that Phil?
Phillip McAvity - I accidentally walked in on Anita this morning 'cause I heard a loud buzzing sound. She was at it hard with that magic wand again; her legs were so wide her Flap's eye was winking at me!

Deli Flaps

Meaty pussy lips. Look like a little pile of shaved roast beef. A little pink in the center and brown around the edges.

Babe got the deli flaps.

I was sucking her deli flaps and she was squirting all over the place.

I could see her deli flaps through her yoga pants.

Flap tash

When the female looks down as the male licks her out and appears to have a pubic hair moustache.

"I hadn't shaved in a while and when I looked down he had a right flap tash"

eg. go to google, image search, moustache, top right hand of 1st page.
