Whether it's "proper English" or not doesn't really have a bearing on whether you'll hear it in conversation
How many people say, "What did you receive for Christmas?" when asking about your gifts? Not many. It's always "What did you get for Christmas?"
I almost never hear, "It became cold last night." People say, "It sure got cold last night."
I'd agree that there's (almost) always a better word that can be used in place of "got", but that doesn't mean the word isn't used in their stead. And, to be honest, most of the time I don't have a problem with people saying it.
The time it bothers me is when it's used in place of the word "have", as in, "I got a Ford pick-up." or "Do you got any snacks?"
