A mountain lion is similar to a cougar, only it refers to an UN-attractive older woman seeking younger men. The only difference between the terms mountain lion and cougar are that cougars are usually somewhat attractive, and mountain lions are usually quite ugly. The mountain lion's natural habitat is at bars.
I was walking back from the men's room, and a mountain lion tried to attack me with a crotch grab!

I thought I spotted a cougar across the bar, but she turned around, and was definitely a mountain lion.

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.

We all know a cougar is a hot older woman who goes after younger men.

A mountain lion is an older woman with the same tastes, but hideously ugly.

The name derives itself from a pun. See example below.
That woman isn't a cougar! She's a mountain lion, as in, "If you said you'd be mountin' that, you'd be lyin'!"
