guddayce 

Good ice or good ass, when something is better than good and is worthy of an exclamatory all it's own.

When she tasted my Ice Coffee she said, "That's some guddayce coffee."

Guddance 

A development of the word good. The addition of the "ance" adds more emphasis on the goodness. The "oo" changes to a "u" during this transformation. Rt.Hon Sir Toby and Miklitoris

"Youre life sentence for being a psychopath has been reduced to 5 years"
"Guddance!"
