Whereas a "Bimbo" is a woman that hyper sexualizes her feminine attributes
to the point of getting large breast implants, lip injections, and
plastic surgery that makes her face look gaunt, a "bimby" or "bimby girl" is a young woman, above the age of 18, but younger than her 30's, that sexualizes her girliness.
This sexualization of her girliness is often expressed by her wearing tiny little skirts that won't completely cover her buttocks, a little shirt that may be a school girl's uniform shirt or a little girly t-shirt. She may be seen with a sucker in her mouth or in her hand, and might wear a little girl's backpack.
While she may look innocent, she actually knows exactly what she is doing. A bimby or bimby girl is actually quite confident in her sexuality and her
femininity, knowing her Man or her Daddy is watching her, and is quite happy about it.
