What are the current useless terms in this "audio world"

@millercarbon When I hear Electrician, I think of a licensed and certified person who can legally work with electrical components, dealing with electricity    
When I hear Professional, I think of someone with a professional education degree first, a doctorate for example    
When I hear that someone ran or run a business, I think of an entrepreneur, for profit, providing a service or product.    

Some words evoke immediate images and are not difficult to assess.

Intimate

@millercarbon -- I've auditioned every car I ever bought. They call it a test drive. It's always nice to know if the seat is comfortable, you can see out of it, and if the controls...as they used to say...fall readily to hand.

it seems that the audition then marriage of a mate doesn’t guarantee good mileage or longevity.

Without a doubt, >$150 AC mains fuses, that are said to also be directional.
THE BIGGEST LOAD OF ** I HAVE COME ACROSS IN THIS INDUSTRY
