To elude detection from unwanted solicitors or family when they knock on your door. Pretending to not be home. It doesn't matter if they know you are home.
There was a knock at the door this morning and when I peeked through the blinds I saw that it was the Jo Ho's again so I Ann Franked them. (meanwhile they saw the blinds move)

A sex position. To do the Anne frank, you must go up into a secret annex or closet of some sort, then have sweaty closet sex while police search for you.
