beach chick
noun a young woman living a Bohemian lifestyle near the beach in the 1950s. Peter Tamony described the term as follows: 'Originally applied to girls who lived at Stinson Beach [north of San Francisco] who were bisexual. By those unfamiliar with its background, and both ways implication, it has been extended to any girl who associated with the so-called Beat Generation inhabitants of North Beach in San Francisco'
