Fancy wancy lemon clancy refers to something fancy in a joking way. This is particularly used in Sydney high schools and is part of the 'lemon' slang branch, which includes phrases like 'sexy sexy lemon pexy' and 'nasty wasty lemon pasty'.
If you were taking the piss out of someone who was posh you would say that their 'fancy wancy lemon clancy'.
