I'm not sure I have. My mind keeps floating away.

Back to SciFi (which incidentally I remember hearing as SciFic somewhere in my distant past) word. It always amused me to see what was invented as swearing. Frac, smeg and the like.

On a tangent, does anyone remember the Tom Swift series. No invention of new words there. They just prefixed everything with space. "Look Tom, the explosion of space fuel turned that space rock into space dust!!!" Yeesh.
