This concept cracks me up because much like Karen, it just makes no sense for it to be named after women.
“But PCL, the concept is named after a female character from a Star Trek fanfiction contest! The original one was a female character!”
Oh I’m sorry, I didn’t know that this Star Trek fan fiction was written after Les Miserables. Or The Last of the Mohicans. Or Planet of the Apes (that might have been around the same time).
Just look at this video on the history of Mary Sues in fanfiction. You had a whole generation of teen girls terrified to write them and cutting each other down for it instead of just expressing each other creatively the way every little boy did that age with Gary Stus.
I am only ever using Gary Stu from now on.
