I talk about this relatively new word in English, which actually has its origin in science fiction. The word follows a common pattern for words that start with a very specific meaning in a field or discipline, and then once they're in use in standard English they develop their own meanings and history. I wrap up by comparing it to the word schizophrenic, which has behaved similarly, but with a bit of a twist.
