Coming Monday: He Called Me a Peckerwood

I Googled various definitions of peckerwood and I didn’t seem to really fit into any of them, at least in my own estimation. Some of you may feel differently. Maybe the guy who called me that meant something else. I don’t know. What I do know is that I can remember two occasions in my life that I’ve been called a peckerwood and neither time was among my prouder moments. Maybe the West Side Wizard can enlighten me on the etymology of the word peckerwood.
