look up any word, like bae:
 
1.
(Noun) A female spokesperson used in television advertising primarily because of her large breasts and overall sex appeal; she is usually blonde, appears to be a bimbo and may even be one, although she may have mastered the ability to memorize and deliver advertsing copy on cue. In local TV ads, she is seldom "professional talent" and is likely to be the wife or girlfriend of the client, the ad agency rep, the TV producer or the account manager.
Have you seen that ad for the new car dealer? They've got some spokesbosom who looks like a Miss America wanna-be!
