The Unwhippable | Theater | The Stranger, Seattle's Only Newspaper:
What do you tell people when they ask what it means?
I heard it as a phrase somebody said in a doughnut shop. I was standing in line and there was a little kid running around wild and out of control. It was South Carolina, I think. And a guy behind me said "must don't whip 'um." "Must don't" is a Southern expression, usually derogatory. It means you can tell someone doesn't do something: must don't wash his hair, must don't shop at fancy stores because he has crappy stuff.
To me, it came to mean someone who is wild and out of control. Or refuses to be disciplined. In the show, it refers to ghosts, because ghosts are a phenomenon, an energy that persists after death, something that refuses to be killed. The unwhippable.
