The old southern meaning of spoof or the act of "spoofing" is to
trick or otherwise
play a practical joke on someone. (This might be remembered from the old "Deputy Dawg" cartoon where the mischievous Muskie the Muskrat constantly spoofed Vince Van
Gopher, Deputy Dawg and Sheriff.)
Muskie: "Depty
Dawg, Depty
Dawg!
Vince fell in the quickmud!"
Deputy Dawg: "Dag nabit! This better not be a spoof, Muskie!"
Muskie: "It's possible... It's possible..."
