1.) Female member of a sporting team's cheer squad. Characterised as attractive, unintelligent/naive, and bitchy; highly concerned with body image, appearance, and popularity. Hyperactively supports, barracks and dances for their team during a sporting event. Usually date and sleep with jock
2.) Female equivalent of fanboy
. Derived from the cheerleaders' blind faith in, and support of, their team. Used in application to figures such as particular bands, actors, ideals, styles, pop culture/television shows, countries, and so on. Like fanboys, cheerleaders are unable to discuss their idol objectively and maturely, rendering conversation with them useless and frustrating. This also makes their opinion on the topic superfluous.
