This phrase is uttered as an exclamation of joy or surprise by the character, Wolf, in the book The Talisman, written by Stephen King and Peter Straub. The idea behind this phrase is a Zen like, primal understanding of the screwed up nature of things. The fact that you and I can deal with everything right here, right now is just another proof that we human beings totally don't get it.
Anything and everything that is right here and now is important.
