The title of this entry is a distinctly Australian version of these, and ties in neatly with the foregoing post (and an earlier one) about ANZAC Day, when the otherwise illegal gambling game of Two-Up is permitted and indeed considered an integral part of remembering former soldier mates. The "spinner" is the person who flips the coins, and is usually drawn from the eager crowd surrounding a game.
I can't say I've ever actually watched a two-up game, and I certainly don't know the rules, but the derisive expression "Come in Spinner" is one guaranteed to make an Australian feel foolish. So, my shame-faced apologies go to anyone who recently received what looks like a friendly email invitation from me. It was unintentional, unapproved, and completely impersonal, so please delete it immediately and on no account click any links.
[Added: Not that I believe in coincidences, but this week is the 30th Anniversary of the first spam email. 30 years. How depressing.]
