- Mince beef (curse if they have it)
The first of these left me rather baffled. "Curse if they have it"? I had visions of going into the supermarket, picking up the mince and shouting, "Hooray! They've got f**ing mince!" Of course, I didn't do anything so vulgar, and I did manage to work out what my girlfriend had meant.
On a similar note - 'minced beef', 'mince beef' or 'beef mince'? Google prefers the first of these, but how about you? Perhaps you call it something else entirely...
