beefcurtains 

the prominent lips or labia minora of a woman's vulva especially the kind which protrude beyond the outer lips such as to form a set of fleshy window curtains around her vagina. Also called batwings after the style of old fashioned Western Saloon doors seen in cowboy movies.

The porn starlet spread her beefcurtains to take on the well-hung stud.

Iron Beef Curtains

This refers to the Vagina of Margaret Thatcher (Former Prime Minister of the UK). The nick name for her flacid genetalia, comes ironically (HA!) from the nick name associated with her stubborness in politics "The Iron Lady".

However the nick name became cemented in the hearts of the public, when a photographer accidentally fell over and took a picture upskirt revealing her vagina to be actually made from 18th century pig iron.

This has opened up a large debate which spans many topics.

Biology - How?
Philosophy - Why?
and Politics - ......

Some have suggested that it was not her vagina at all, but a form of securtiy device to stop unwanted vermin from nesting in there. However regardless, the media splash was enough to concrete in the term Iron Beef Curtains.

I would like to be the first, then, to suggest, that instead of wasting, millions of pounds of taxpayers money on her state funeral. We should instead, recycle her Iron Beef Curtains.

Beef Curtains 

the creul term for long, hanging inner labia. Despite popular belief, it CAN NOT be "caused" by repeated insertion of a dick. Those who have them are simply born with them.

Did you see the beef curtains on that girl?
Hell yeah I did! Let 'em hang girl!
