Maybe I'm missing the point but: Selling a covered call means you hold sufficient shares to deliver as obligated. Selling a naked call means you do not hold sufficient shares to deliver as obligated. Selling a covered put means you are short sufficient shares to "buy" the shares as obligated when you "buy to close" your short. Selling a cash secured put means you have sufficient funds to buy the shares as obligated. Selling a naked put means you are not short sufficient shares, and you don't have sufficient funds to buy the shares as obligated.
I trade equity volatility for a fund and we are quoted a volatility when dealing with agencies or bank desks. I have never been quoted the neutral position and I think I would remember the naked part.
"Naked" is European equivalent for "live". Also, when we say "tied", they say "covered". There are many NSFW jokes that can be made
