I was talking to a friend recently and we were saying that you never seem to hear the word smorgasbord any more around here. I know that although they are slightly different, it was used interchangeably with buffet, and then one day buffet just took over. I think it's a shame as smorg was a lot more fun to say.
Skidoo is still used around here a a lot as it's a brand of snowmobile, and is often used as a verb like, "we went skidooing last night".
Nowadays I think you'd only hear 23 skidoo if you're at like a vaudeville type show and someone is getting vanked off stage with a hook. Haha. Certainly a fun word and image.
Smorgasbord has never been interchangeable with or used as commonly as buffet. If anything it would just be a selection of cold cuts that might be called, by some, a smorgasbord. Nobody calls a table of meats, a buffet.

Similar is not the same. They were not interchangeable. Showing a non food-related example of smorgasbord does not help your argument. Just reinforces the impression that smorgasbord is most often used pretentiously.
Regardless of the similar definitions, historically, they weren't really interchangeable. They're only interchangeable in the same way that some characters like to say "madam", "filly" or "bitch" when they are talking about a woman.
Go to a restaurant and ask for smorgasbord and then wish you'd asked about a buffet.
