Expat I am!
I am an Expat!!! If you check Wikipedia for "Expat" you will find two explanations.
It is an XML parser (I am not an XML parser --- if you are a software engineer you know what it is).
The other explanation is "A shortened version of the term for Expatriate" which is a person temporarily or permanently residing in a country and culture other than that of the person's upbringing or legal residence. There is an Expat blog where you can read info about people living abroad. The Telegraph.co.uk even have an area with Expat info.
ps. there is actually an indie rock band called the Expatriate.
