A "bunny girl" generally refers to a Japanese term given to a Playboy bunny, especially one who wears a bunnysuit.
But some images having this tag do not refer to the Playboy bunny, but simply a female human or anthromorph having rabbit ears, but not necessarily the other elements of the Playboy bunny.
