In Belfast, if you enter a fast food takeaway and ask for a fish supper, the server may well ask "what's ur cawn" in a broad Belfast accent.  To which you might reply "fanta".  Over the years it has become commonplace to use this phrase as a greeting. So, instead of "what about ye?", you may say "what's ur cawn?".
