Bimbo

Bimbo is a derogatory slang term for an attractive but unintelligent female. The term was originally used in the United States as early as 1919 for an unintelligent or brutish male.

As of early 21st century, the "stereotypical bimbo" appearance has become that of an attractive woman, often blonde and with a curvaceous figure and large breasts, possibly wearing heavy makeup and revealing clothing. However, none of these traits are strictly needed for a person to be considered a bimbo. It is sometimes associated with men or women who dye their hair blonde indicating that physical attractiveness is more important to them than other, non-physical traits and as an extension to the "dumb blonde" stereotype.
