I'm not a betting person, but I'm certain that today's citation for 'spam' (Monty Python) does not refer to computer-speak but to a ubiquitous staple British foodstuff "Spam" (R): a tinned meat product consisting chiefly of ham, and loosely, any tinned luncheon meat.

I'm not sure how widespread it is today -- any British foodlovers care to enlighten us?
