I know what you mean!!!

Stumpy - I don't have to google the word - but I wish alot of people would, then they wouldn't misuse the word so much.

why do you think somepeople misuse it :-)?

i would like to add to the definition
it is someone who is planning to move to other country as well
even if he is still living in his original country :-)

No it's doesn't.

The term purely means people living outside their native country (country of origin).

biffy,
Although it seems that you are looking for the literal definition of the word "expatriate", however, I believe there is a deeper discussion "meaning" behind such a question.
Therefore, could you please explain to us "based on which terms" how you define the misusage/misunderstanding of such a word?
Also stating some examples about the misusage/misunderstanding of the word "expatriate" which you have experienced "on this site" will help to focus the discussion.
