I am always fascinated by jargons, be it trade jargons, sports jargons, or others. You pick up something new everytime you hear a conversation or a discussion among people in the same field.
The other day, I was seated in a restaurant next to a table of medical professionals and I heard something like an ekg machine and other difficult-to-pronounce machines that sounded alien to me.
Along the same tone on jargon, a girlfriend gets agitated every time her husband talks insurance-gibberish at home. LOL
