My great grandfather was bestowed with this. My father, when asked to say papa (this was when he was months old) responded with "Gug" so he started to be called Gug. This gentleman had a habit of calling everybody 'buster'. He did this with my older sister when she was like 4-5. So she called him "Buster Gug" and from that day on, that became his name to the entire family. I actually don't even know what his real name was. He died when I was young but he had a name given to him from 2 different generations.
