look up any word, like smh:
 
1.
A woman, attracted to younger males (usually in the grade below), with claws that come out on the weekends. The Mountain Cougar manages to leave marks on one's body, usually in the form of scratches and/or hickeys. People are often amused by her behavior, giving her the title The Mountain Cougar, or "Cougs" for short.

The Cougar goes wild on the weekends, and lives worry-free. She often hibernates in cars, and has to be home extra early to sharpen the claws.
Hungover Friend: Dude, look at your fuckin back and neck! What the hell happened to you?

Victim: I was attacked by the Mountain Cougar this weekend
