I couldn't find it under the newbie acronyms list.

and I forget the last one, but it's a big wing-ding that the adult video industry has every year at this time in Vegas and I hear it's a hoot.

It actually stands for a publication that represents the industry.  The wing-ding is there annual awards presentation and convention (sort of).

AVN=Adult Video News.
AVN Awards, are in Vegas next week.
AEE=Adult Entertainment Expo, the accompanying trade show.
