What does the word bimbo mean?

bimboQ. What exactly is meant when someone is called a “bimbo?”

Adam answers:

A bimbo is a derogatory term for a woman who is attractive in a showy sort of way — think lots of makeup, jewelry, hairspray — but also either dumb, promiscuous, or both.

Used in a sentence: “I can’t believe he had an affair with that bimbo when his wife is so beautiful and nice.”
