OK, maybe, it was the first one I came across. Well, you can claim they invented the term in 1998 and I guess I can't convince you otherwise unless I dig up some old documents, which is unlikely.
Anyway, FWIW, we used the terms "open source" and "open source code" way before that and it was widely understood. I don't have any reason to make that up.

Perhaps it was your personal jargon. I don't see any evidence that it was widespread before 1998.
I think it's more likely that your memory is failing, and OSI's campaign was so successful that they really convinced you that you always called it "open source". It has been close to two decades, after all. We can forget.
