Ever read the book, "How I Survived Middle School: Can you get an F in Lunch?" Because this is almost the same as it... just it's at a middle school, the prank the 8th graders pulled on the main character lead her to the janitor's closet, she didn't walk in the boy's locker room, and the main character's shirt didn't say "I'm the BIG BAD WOLF", it had a lizard on it from the camp she went to.
