grammar - Use 'got' instead of 'was'?

Why is “to get” sometimes used where “to be” could be used?

Sometimes I hear people say things like this:

I just got robbed.

(Personally I would rather say 'I was robbed' or something.)

It seems correct to me, but is this a good style? And if so, in which cases is it possible to replace a word with get or got?

Answer

In American usage, got means became. Just as I just became robbed, while technically correct, is not used, I would not use I just got robbed, preferring was. In some cases became would work, and so, then, would got. (I just got married comes to mind.)

I can't speak for British English.
