Use 'got' instead of 'was'? [duplicate]

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?

My personal impression is that formal use of got with past participles should be restricted to the case where the past participles can be considered as adjectives. For example,

I got married.
I got excited.

are fine, because "married woman" and "excited man" are reasonable expressions. However,

I got robbed.

should not be used in formal speech, because people don't generally talk about "robbed men." Also note that I was excited means something different from I got excited.
