A woman in her late-thirties/early forties who finds herself single after several years of marriage (ususally not of her own choosing) who has no idea that men find her attractive, esp. younger men or 'cougar bait.' Her years in 'captivity' have stripped her of her ability to flirt and land men, even when they 'lay at her feet, like a deer baring it's neck'
"OMG, I can't get that chick's attention"
"She's a Zoo Cougar"
