Grammarian wanted!

It is either an obscure reference to the "beast with two backs" or means that everyone else is safe because tigers have no natural enemies and by fighting they cripple each other.

I'm more inclined to see it as a euphemism for lusty sexual congress.......

Toto lyrics aren't meant to mean anything (Mounts hobbyhorse). Consider some of the lyrics to their seminal work Africa...

"The wild dogs cry out in the night,
As they grow restless longing for some solitary company.
I know that I must do what's right
As sure as Kalimanjaro rises like a memphis above the Serangetti
I seek to cure what's deep inside, frightened of this thing that I've become."

I mean to say, FFS, really.
