Every once in a while, you see a word so badly misused that you can take pleasure in knowing that the speaker (or writer) has no idea what he's talking about; or alternatively, that a word has acquired a ridiculous new meaning. I felt that way years ago, when I received a spam email from a porno web site that boasted: "we only use professional amateurs."
Well here we go again: I received a four-page ad for a course on estate planning and retirement. The glossy says, in big bright letters: "This 3 session course is not a seminar!" Now what could they mean by that? The next sentence of their brochure explains: "No companies or products will be mentioned." Now that's a seminar.
