Well, it's been demonstrated that at least some medicine is a waste of time, if not actively harmful. I imagine that, confronted with a layman who flings misused medical terms about, the average doctor would think him/her a pretentious bore at best.
I've found fools uneducable, and I don't use the term "bokeh". Instead, I use the words "rendition of out of focus areas" which are accurate, self explanatory, and at least somewhat understandable to the unitiated. The purpose of language is communication, jargon is understood only by the elect. I personally find jargon annoying.
"Rendition" is the completely wrong word FYI
