A none-too-
clever euphemism for the planet
Earth overused in pulp
science fiction paperbacks and B-class movies of the
MST3K ilk.
Example:
"Where did this being come from?"
"A lonely little planet called 'Dirt', I believe."
"'Dirt.' How amusingly provincal."
{All cackle patronizingly at the Hero}
This kind of nonsense is exactly the sort of pablum that talented sci/fi writers rail against with every breath. Fight it in everyday life by carrying a pocketful of soil with you everywhere. Remind yourself, when shaking earth from your wallet and keys, that our planet is named Earth because we live on the ground, grow our food in the ground, and are buried in the ground.
Don't like it? Move to another planet.
