He went in back of the curtain

I can't tell. Can you provide a quote?

In back of the house. behind the house, in the back yard.

This phrase is a coloqial Aamericanism, not used elsewhere in the world to my knowledge.

Not to be confused with Outback a word for the desert country of Australia.

Well, dadpad, I'm from America, and I never heard this expression. My first thought was that it had something to do with theater--or maybe window treatments.

perhaps its a regional thing roberta. I certainly have heard it on movies or TV programs from the US.

That's it. Thanks.

Really? If I was the curtain I would be of the right mind to give him a good ol' Rogering....

excuse my poor English.
