What should I do with "lil stinks"?

I get used to calling Grant names like "Lil Stinks" bc John is always singing silly songs and naming him silly names. For those that know John very well- I know this is not hard to believe. John can make and sing a song over and over using as little as 3-4 words. And sometimes the words aren't even real words. The thing is- Grant loves them and they are soooo funny. So... Dad often calls Grant "Lil Stinks"- and here he is being a little stinker...just like his daddy!
