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

ROTFLMAO! 
Engineer (recording, electrical, fill in the blank)   
Electrician    
Professional    
ran a business    
run a business     
build quality  
geometry     
quantum    
tunnel   
Tesla     
audition (you tried it, okay? Did you "audition" your car?)

It’s sounds like the day it was recorded. Who the hell was there that day. I guarantee most are not old enough to have attended the recording or even have been invited to. Talking about the analog days. 

@millercarbon  Nope, when I hear the word salad, it means to me a mixture of various foods, generally cold and generally food in small size pieces.  It could be a fruit salad, vegetable salad, tuna salad, chicken salad, potato salad, etc.  Not necessarily involving a vegetable (fruit) or predominantly involving a vegetable (tuna/chicken).

@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.
