Used to describe something very impressive, delicious, great, smart or anything you really like.

When something is even better than Guff then it has lots of Guffness.

Or the Auzzie Boys Gang.

Your brain is full of Guffness today. (That is a very Guff idea)

Thankyou for this meal, Guff, Guffness.

When you see a hot chick you say "Guffness".
