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

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.

"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.
