InterWeb.

I think I first heard the term used, while working for a small Internet company, by an Aussie. I can't recall whether we were laughing at him or he was laughing at us.

Anyway, I now use 'InterWeb' at dinner parties, hotels and even in the work environment. People used to stare quizzically but, sadly, no longer. The term is now in common usage which somehow just makes it all the more amusing.
