That's interesting--I definitely think there's enough clues there to make them a *type* of girl, but as with teachers like Snape, we probably have different associations with them. Like, for me "dislikeable" is not one I would associate with this type of girl. I might not be friends with them, but they seem more silly than dislikeable. But that's probably got to do with people filling things in from their own experience. Rowling wants me to love Ginny, and post-OotP she's probably the only character I really consider unlikeable.
