Somebody who when discussing an event in the news such as a criminal case, decides that the punishment
meted out is not enough.
While mostly ignorant
of much of the story, the gnarb-gnasher leaps on the bandwagon to have them not just punished to the full extent of the law, but punished horribly
. They get quite creative
in saying what should be done to them. It's really scary when you get a lot of them together and they begin to sound like a lynch
The gnarb-gnasher is talking about Tiger. He says, "Tiger Woods cheated
on his wife. He should be taken out and horsewhipped
and left in the countryside for the birds to pick his brains"
"Oh no," says the other gnarb-gnasher, "let's cut off his narbs
and make him eat them. And then roll him down the hill and leave him for the cars to run over his bones!"
