To place one's arm across another's shoulders while placing a forceful grip on their arm so that they may not escape. The iron curtain is completed when you let all of your body weight rest on the other person so they are essentially holding you up. This act when preformed on women could lead to being bunned if extreme caution is not exercised.
Person 1: "Man, he was so drunk last night, I totally got the iron curtain."
Person 2: "At least you didn't get bunned"

A phrase used to describe what you think a girl who is very conservative would look like naked.
Guy 1: What do you think is behind the iron curtain?

Guy 2: Rita? I bet she doesn't shave her vag.

Guy 1: Man that's nasty. You know I'd make sweet love to her.

Guy 2: You would make sweet love to a girl who doesn't shave her vag.

Guy 1: Man you don't know that. Nobody knows what's behind the iron curtain.

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.

The "Wall" of Iron Balloons sent out mid-game while playing the iphone game "Balloons Tower Defense Battles." It is unavoidable. It is defeat.
