M&S used to do really nice Beef and Tewkesbury Mustard bangers. Haven't seen them on the shelves for donkey's years though.
An Aussie CB/RB who played for my football team at college was telling a group of us in the common room bar one day that Australian slang has a collection of euphemisms for the male member. The above expression could easily be one, but didn't figure on the list as far as I remember. I do recall "pork sword", "veal dagger" and "beef bayonet".
Yes - I once met a German who referred to it as "playing the beef trumpet".
Unfortunately he was male - otherwise I'd have a list of tunes I'd love to hear.
