Interesting that 'icing' seems to be used more in certain parts of the US and 'frosting' in others. I'd like to get a fix on which is used where. Around here (mid-Atlantic USA) it's nearly always 'icing'. How about you Brits and Antipodeans?

Another set of words like this is 'dressing' vs. 'stuffing' and 'filling' (referring to the savory mixture that goes into a turkey, or a roulade, or pork chops, etc., or which is served by itself as a vegetable in Pa. Dutch eateries and called 'filling'). We use both 'stuffing' and 'dressing', and there is no rhyme or reason to which one is used when. How about the rest of you?
