Hot and sexy older woman, usually in her 40s or 50s, single or married, who is sick of her same-age counterparts which are usually hairless, have big guts, who only talk about their insurance premiums and have the TV remote control attached to their hands. Cougars are attractive, in their sexual prime, who know what they want and aren't afraid to go after it. BIG misconception is that they dress cheap, wear hot pink nail polish, animal skin prints and are not-so-attractive old-looking hags with bleached hair (Yeah those women exist, but they are NOT cougars). True cougars are classy, beautiful creatures who have made their successes on their own, have real brains, usually with expensive cars/homes, and are real head turners. Cougars seek younger men, and don't have to sneak up and attack...they know their younger mates are eager to get an experienced woman who won't ask if they'll call them the next day. Being a cougar is a positive thing.
