An older woman who frequents clubs in order to score with a much younger man. The cougar can be anyone from an overly surgically altered wind tunnel victim, to an absolute sad and bloated old horn-meister, to a real hottie or milf. Cougars are gaining in popularity -- particularly the true hotties -- as young men find not only a sexual high, but many times a chick with her shit together.
That cougar I met last night, showed me shit I didn't know existed, I'm goin back for more.
