I'm a nerdcore rapper, Dr Proximo (rhymes with "domino", not "Pacino") is my rap name. I happened upon the word proximo playing Words With Friends while I was struggling to come up with a rap name (I did a bit of rap as 'kadeem' in the 90s but that era belongs firmly in the past; I had been making glitch music under "Ugliness Man" and EDM under 'johnjack'). since the word has to do with the passage of time (it means "a month from now" or "within the next month"), and my slowly-developing fictional persona had an interest in time travel, it seemed to fit perfectly. the avatar is from my Xbox 360 profile that I haven't accessed in a few years, it looked surprisingly similar to how I looked back then; I no longer wear the hat and usually have facial hair, but I still like the picture. some day soon I should get a screenshot of my Mii in my Miitomo app and start using it for stuff, it looks more like my current self.
edit: since this post is still fairly recent and might be confusing, I just wanted to edit to mention that I've now changed it to a recent Miifoto, as I was considering.
