You keep using that word: on "Mary Sue"

(Most of this post came up in a friends-locked comments dialogue with horridporrid, who very patiently explained her views until I finally got where she was coming from. I've been lax in keeping up with the rest of the debate, so it's likely this has already been stated elsewhere in this debate. But anyway.) Putting aside issues of writing standards and mocking other fen, it seems the big problem with the term "Mary Sue" is with its imprecision and its gendered nature. The basic concepts, I feel, are sound - but we need another word for it.

As I see it, (  there are 3 differing but related definitions for 'Mary Sue': )

The thing is, all three of these definitions are valid critical concepts - even the last, while quite subjective, can explain why a story may be unsuccessful for much of the audience. This is not to say that they're justifiable reasons to trash a young writer's confidence, but they are extant and common tropes in fiction (fan and otherwise), so it makes sense to have a label for them.

The problem with the current label is that while such chars can be male as easily as they can be female (Rodney McKay could certainly be considered one!) defining them with the gendered term "Mary Sue" means that female chars are much more likely to be described as such; it became an easy go-to criticism of female chars, while rarely applied to male chars, a very unfortunate double standard, especially if it means that writers become hesitant to write female chars (afraid that they'll be labeled "Mary Sue"s) while not giving the same consideration to male chars.

So it seems to me we need a new, gender-neutral term for this concept. Any thoughts?

ETA: Apparently ElfQuest had "Wottaguy/Wottagirl" for the original Mary Sue - much less gendered, maybe I'll start using that!
