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

It's F'in Great, It sounds Pretty F'in Good. It sounds like Shxxt. It's F'in Awesome !
Those are my Audiophile terms and I use them regularly with friends and on YouTube.

I too am wary of terms like "reference" and phrases such as "state of the art", but when used by an experienced reviewer, who I have followed over the years and who subsequently purchases the item for use in his/her review system, this certainly carries more weight for me. Hyperbole is the stock in trade of some reviewers.

It's the difference in lifestyle for me.
