Meaning – a large American wild cat with a plain tawny to grayish coat
If you’re trying to rope a cougar, then you’re trying to land a woman who’s significantly older than you. We still don’t know how Americans came to compare this feline to a MILF. If you really want to tell your friends that the lady you’re with is older, then you might as well be clearer with your words. Tell them that you’re trying to rope a saber-tooth. You can’t get any more ancient than that and the phrase just makes so much more sense!
We can imagine Shakespeare rolling over his grave with these expressions. We don’t know why people think it’s okay to bastardize the English language. But the saddest part of all is that everyone is actually guilty of saying a phrase or two.
