band chick noun a woman who is attracted to, and makes herself available to, musicians US An early term for what would come to be known as a “groupie”.
Although Miriam had known enough musicians and enough Negroes to judge each one on his own, there were “band chicks” at the Savoy, as at nearly every club where jazz is played. — Nat Hentoff, TheJazzLife, p. 20, 1961
