No great reasoning for my name.
I was looking on OJ, and for some reason I needed to make an account to do something on the site. Might have been to vote on a poll or something, never expected to be an active user. I just wanted a name that was pronounceable. So ran through a bunch of letters to come up with a name and came up with Zemmi, my friends over time have shortened it make jokes with it ect. Now just a short Zem works.
I did try to change my username once on OJ, but the community didn't accept it and refused to call me anything but their many different versions of Zemmi lol.
