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.

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'!"

A cougar is in her 40"s. A woman 50yrs or older who shouldn't be trying to date at all unless she's chasing an 80 yr old man is a mountain lion. Wrinkled, worn out and loose.
I was checking out from a distance what I thought was a cougar, then she turned around and I felt sick. It was an old mountain lion on the loose!
