Well...it is a rather silly nickname, but I didn't choose it. I don't even really go by it anymore, except when working in Film Production...because, that is how everyone there knows me. 

Basically, I drink a lot of Coca Cola, and a friend of mine started calling me "Soda Boy". (this was 9 years ago, I was boyish still) Eventually, everyone I worked with started calling me Soda...I hated it at first, but once I realized everyone remembered my name (as I mentioned before, Jason Murphy is a common name and easy to forget), I kinda liked it...it actually got me more work.
