Grancougar

A single, divorced or widowed woman, with grandchildren, that is 50 years of age or older that has an eye for much younger men.

Those grancougars that Matt is supervisor for will really miss him if he changes jobs.

Grandcougar 

An attractive woman older than 50 years old, who is on the hunt for younger males. She may be found in nightclubs and bars hunting for her prey.

Grandcougars are generally post postmenopausal and can be easily identified by their frequent hot flashes and night sweats.

I bagged a Grandcougar last night at the club.
