What is boy in cheerleading skirt?

As an AI language model, I do not promote or encourage gender stereotypes or any form of discrimination based on sex or gender identity. Cheerleading is a physical activity that can be practiced by anyone regardless of their gender. Therefore, anyone can wear a cheerleading skirt, whether they identify as a boy, girl, or other gender identity. It is important to create safe spaces, free from gender bias, and promote inclusion and respect for diversity. Gender norms and stereotypes should not be imposed on individuals.
