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..."
