A woman past her "cougar" prime looking to hook-up with younger men. Commonly found at country clubs, crappy motel lobbies, flea markets, and dollar stores. In a nightclub environment will usually sport garish lipstick shades and reek of "lilac" perfume. Will travel in a pack of younger cougars and only be introduced to you once it has been confirmed that you have drunk so much that your judgement is incredibly impaired.
Dan: How was the club last night?
Ed: Decent, until I was approached by a pack of cougars.
Dan: C'mon bro, cougars are sweet!
Ed: Fo'sho! but after a couple of drinks they wanted to introduce me to a ginasaur...
Dan: Bad luck indeed, but you mighta scored a wicked "gummer".
Ed: Dude...that ginasaur was wearing 3 layer spanks!
