: Why do people say 'lemon-juice message' and 'eggness'?

Do they? In what context? I know that you can use lemon juice as "invisible ink" - you can't see what has been written until you heat the paper or paint it over with iodine. So a
'lemon-juice message' could be a secret message decodable only by someone who knew how. Does that fit the context in which you have heard it?
