It takes a special sense of humour to make up a meaning for your name, and keep changing it as and when. The character Agastya Sen (from the book English, August) used to do that. 

Actor Kay Kay Menon, I realise, has been doing it for years. Over a decade and half ago, I think he told me his name Kay Kay was Hebrew for ‘victory’. On a recent chat show, I heard him say it’s Chinese for ‘victory’. Decide, bro. I had to ask him again—no, seriously, what is Kay Kay?
