Girl has stereotypically boyish traits. Derived from the term "tomcat" for a male cat, the Tomboy is a major character archetype and yet is also a somewhat vague concept, and it is associated with the gender variance/nonconformity. A tomboy is a girl who has tastes and behaviors usually associated with boys. Because these associations are culture-dependent and tend to change, what exactly constitutes a "Tomboy" is subjective.
