A woman far too old to be a cougar, who even though she no longer has IT, continues to pile on makeup and chase much younger men. Martha Raye was an example of a true saber-toothed tiger when she scored that gay guy before dying.
Dude, I banged a saber-toothed tiger this weekend. She popped her teeth out, blew me and then gave me some milk and cookies after we finished up in the sack.

Saber-tooth tigering is a step beyond what a cougar does. Instead of a lady in her late 30's/early 40's, its more like a lady in her late 50's/early 60's.

This is a step beyond cougaring, because

This lady is basically a horny old grandma that nails younger men.
Holy shit! Grandma is saber-tooth tigering that groomsman!

A female species who is much older than a puma, and even beyond a cougar. This is an woman classified as a senior citizen (65+) who frequents dive bars to get lucky with a significantly younger gentleman. She is usually spotted in her native habitat, dark seedy bars on the wrong side of town drinking vodka by the pint.
No one ever goes to that bar anymore, too many Saber Toothed Tigresses scared away all the cougars.

Like a cougar, but older. Whereas the term cougar refers to an attractive, seductive woman in her late 30s and up, a saber-toothed tiger is an attractive, seductive woman in her late 50s and up.

A Saber-toothed tiger is also referred to as a "smilodon".
"Check out that cougar by the bar, man! She has been eyeballing me all night."
"Cougar? She's older than cougar, bro. That right there is a saber-toothed tiger."
