Tiny Tyrannical Girl

She's small. Short. Petite. Vertically challenged.

She tells everyone what to do, and expects them to obey. Threats ensue if people don't. Sometimes even physical violence. Maybe she's compensating for something?

Perhaps it's the incongruity of a small young girl ordering people around as if she were the big alpha male, but it's a pretty common character design. Some people think she's cute. Others think she's annoying. Either way this is a visually and verbally striking character, and is rarely forgotten. Making large men the target of her orders just adds to the fun.

Often justified by having her be a spoiled rich kid, or even royalty. Other times, she's just the only daughter in a family full of males, and her older brothers spoil her immensely. Usually she's pre-puberty age, but sometimes it can creep up into the teen years. It's possible for her to have character development and learn humility but other times she'll never learn.

Certainly some Truth in Television, as plenty of parents and grandparents can confess to being amused by their daughter ordering them about in a very decisive manner.

Compare The Napoleon and Bratty Half-Pint. The Shana Clone archetype is a notable subtrope.

Film (Live-Action)

 * In Remember the Titans, pretty little blonde Sheryl Yoast yells at the football players as she assists her father coach.

 * Several of the not-yet school-aged divas on Toddlers & Tiaras. One show had a 4-year-old ordering her mother around and haranguing her for not doing things right. Cut to the Confession Cam as her mother praises the behavior for showing her daughter's "dominance".

 * The Nostalgia Chick is a rare example of an adult woman being this. She's 5'2" and tries to invoke Kawaiiko but is really a Psychopathic Womanchild and is dominantly abusive to everyone.

Real Life

 * This poor boy knows you're doomed when one of these girls decides to marry you. You'll find plenty more like this on YouTube. Demonstrating that it's not just amusing in fiction (as long as she's focused on bossing someone else).
