The Evolution of a NickName

Nick Names are very cool. Terms of endearment that facilitate a bond between individuals (no, that's not a dictionary definition - that's ALL me kids). So, I would like to illustrate the genesis and evolution of how one might obtain or dub another with a nick name. Often times, a nick name is similar to the person's real name but it begins a meandering path off to something very different altogether. See the example below for my cat Kobe (yes, like the baller not the city).

Kobe ---> Kooby ----> Kublai Kahn (sp?)
OR
Kobe ---> Moby -----> Moobs ---> Moops ----> Moopy Moops (see, isn't this fun?!)
