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

Warm sounding 
Tube Watts 
Listening to wires and entertainment stands

End Game - Who are they kidding?

Musical
Analytical
Fast
Lush
Warm
Airy
Presence
Delicate
Sparkle
Speed
Texture
Veiled

All terms with non-specific meanings that are open to wide interpretation or are mythical (like a 'fast' subwoofer), and therefore useless. I'm sure there are many more I've forgotten.

Snake Oil... If it works for you, it's the greatest thing in the world. 
"Try it you'll like it"  (you older folks will remember this one although nothing to do with audio).

A term I don’t like, but doesn’t squarely fall under “useless” is “high end” audio. I much prefer “high fidelity” audio because I can tell that to those not in our hobby “high end” is interpreted as we are more concerned about price and bling than what is most important - the pursuit of high fidelity sound. I for one am certainly not seeking out “high end” audio when looking through this perception lens.
