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..."
