A Cougar past its prime. But still ferocious. An elderly woman who secretly chases after the friends of her grandson. Well past menopause but somehow has still maintained that eerie sex drive and is unappologetic in voicing her sex advice, advances and wisdom to her friends and family.

With the advent of Cialis and Viagra, and other ED drugs it has brought to the forefront the truth that not only do older men way past their prime still maintain unusally high libido but their older, pastier counterparts do as well.
Dude, why does your grandma keep asking me if I want more milk and cookies? Watch out, bro, She's a mountain lion.
