Temari. If she were visiting the Hidden Leaf Village and got involved in some sort of friendly chaos with the local ninjas, perhaps a wedgie could be part of the comical events. She's tough but that would still be an embarrassing situation for her.

The girl herself is the central character. However, depending on the nature of the story, there could be other significant characters. If it's a story about revenge or getting back at someone who gave her a wedgie, there could be a character who helps her plan her revenge. Or if it's a story about growing up and learning from an embarrassing experience, her parents could be important characters as they might give her advice on how to handle such situations at school.
As I don't know the details of the 'Atomic Girl Wedgie Story', the main character seems to be this 'Atomic Girl' from the title, but there could be others involved depending on the nature of the story.
The main character would be the nerd girl herself, who is probably shy, intelligent, and loves things like reading or math.

But again, this is all speculation without more context.
