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.
