(名詞) 想要「老牛吃嫩草」或跟年紀比較小的男子發生性關係的中年婦女。cougar 原意為「美洲獅」。參見 manther

Besides being dressed in a tight pair of jeans or (weather permitting) body-hugging dress, the cougar can be identified by three key characteristics. First, you'll notice that make-up has been liberally applied to the mouth and eye area. Second, her clothes will be cloaked in a heavy veil of overly floral perfume and, third, quite unlike the younger members of the female species, she'll have no qualms about getting raging drunk.

Speaking to The Sunday Telegraph during Harper's Bazaar's Women of the Year Awards, where she won a prize for Role Model of the Year, Thompson said: "It's easy to be flattered, but I am no cougar. I've had a lot of male attention here from budding young actors asking about getting on in show business...It got me thinking about the cougar thing. I am a happily married woman, but, even if I was single, I wouldn't be up for it."
