According to Wikipedia, a Bond Girl is a character or actress portraying a love interest of James Bond in a film or novel. They occasionally have names that are double entendres. Bond Girls are often victims rescued by Bond, fellow agents or allies, villainesses or members of an enemy organization, most typically the villain's accomplice, assistant or mistress. Some are mere eye candy and have no direct involvement in Bond's mission; other Bond Girls play a pivotal role in the success of the mission.
My current favorite: Honey Ryder (Ursula Andress) for her swimwear obviously.
