Tomboy

A girl who doesn't wear makeup, or try to keep up with the latest fashion, she doesn't care what her hair looks like and is not afraid of expressing herself. Typically enjoys things that others might consider "boyish" like climbing trees, skateboarding, or playing in the mud. Tomboys tend to be more into sports, and will typically prefer to wear jeans or other comfy clothing.

I love climbing trees, and I hate wearing dresses. I am such a tomboy
