Bimbo is a term that in popular English language usage describes a woman who is physically attractive but is perceived to have a low intelligence or poor education. The term can also be used to describe a woman who acts in a sexually promiscuous manner. The term itself is not explicitly negative, but is most often used as a derogative insult towards a woman.
Use of this term began in the United States as early as 1919, where it was used as a slang term for an unintelligent or brutish male. Its first inclusion in an official dictionary for its female meaning was in 1929, where the definition was given simply as "a woman".
The term Bimbo is often associated with, but is separate from, the stereotypes of "Dumb Blonde" and "Valley Girl".
The first usage of the term Bimbo in English was for an unintelligent male, although it now most commonly used to refer to a woman unless modified as male bimbo or himbo. ...
In 2010, the Daily Mail reported that some research has suggested that women with low IQ - termed "bimbos" by the Mail - may seek to compensate this by seeking more materially secure and stable spouses in a variant of Darwinian sexual selection. This behavior may be the root of the 'gold-digger" aspect of bimbo stereotypes.
