Little Miss Slammer

An idea I thought of.

A popular teenage girl went to see a wrestling match with her friends. Which she's not a big fan, but only went to be with the cute boy he has a crush on. He got lost while going to the restroom, and suddenly found herself in the ring and accidentally blurted out that she hates wrestling and thinks wrestlers are "small-brained, dome-headed neanderthals". And this got the lone wrestler who "won" the match very mad and starts beating her up. The referee tried to stop him, but the wrestler punched him out of the ring. Her friends and everyone in the audience and the viewers are horrified for the poor girl. Tired of always being "pushed around" by everyone, she had enough and starts beating the crap out of her in amazingly quick moves. The audience and the viewers cheer for her victory.

The next day, she was offered to join the federation as the first teenage wrestler. Her most embarrassing moment is when she has to share the dressing room with the adult male wrestlers. She becomes one of the most popular wrestlers, making her even more popular in school (though the downside is some kids make fun of her for it). Her family has become very rich from her endorsements. And she has to juggle the culture shock of actually playing in the mostly male-dominated wrestling arena; working with one of her brother's heroes, an aging wrestler; and time with his friends; and her schoolwork. But she also has to deal with people who wants to use to more money and jealous competitors.

Unable to endure the "burden", she decides to quit after the next championship, which is where the stakes are high.
