A woman hitting on younger men whose age puts her far beyond the "cougar" category
I knew Mike had a thing for cougars but when I saw a 55 year-old lady talking to him, I realized he had transitioned to saber-tooth tigers.

Dude, me and Matt saber-tooth tigered Sheena last night! ...but...that doesn't mean we're gay or anything....

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 woman older than 80 who stalks men much younger than herself in order to quell a post-menopausal sexual arousal. A Saber tooth tiger is older than the puma, cougar, lioness, and jaguar.

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."
