Where the Cougars Are

When I saw the Headline: Where the Cougars Are in my september National Geographic (which I've just gotten a chance to read now at Thanksgiving) my brain first processed the word cougar as in a woman of a certain age or maturity who dates much younger men. WHAT IS WRONG WITH ME?! Also, what is wrong with the definition of Cougar on urban dictionary? I'm awful at spelling - this entry is criminal. For shame!
