I have heard many men call female characters a Mary Sue. The only time I’ve ever heard anyone call someone a Gary Stu is in a sad desperate attempt to defend their use of Mary Sue.
Is that a joke? In this very thread someone (who seems to like the Rey character) replied to me with this post:
This is a good, well reviewed book:

The main character is a Gary Stu.
Discuss. Or better yet, let’s not.
And whether or not anyone uses the term “Gary Stu” for a male character is irrelevant, because it has nothing to do with the fact that it isn’t a sex-specific term. It is a character-type specific term. The name of the trope, “Mary Sue”, was taken from the name of a character used in a parody that was written specifically to demonstrate this type of character.
You want to argue that Rey does not earn her abilities? I disagree with you, but feel free to make the argument.
You want to do it in a derogatory way? Congratulations.
You don’t get to redefine the term “derogatory”.
Also, rating TFA a -1/10 has always been and will continue to be nothing more than a troll move to illicit negative reactions. So again, congratulations.
You don’t get to redefine the term “troll” either. If I don’t like a movie at all, I give it a 1/10. I don’t rate movies based on technical merits such as production values and such; I rate them strictly based on how well I liked the movie. It is the same score I gave it on IMDb the night I saw it in the theater in 2015.
