It's a bit of a long story, but I'll tell it anyway. I was looking at joining a different forum back in November 2012, and I wanted a cool username. I also wanted to do a mash up of two names. I figured, two of my favorite wrestlers of all time are Chris Jericho, and Kane. So I combined Jericho and Kane to create JeriKane. Originally my number at the end of my name was 1234. But around my birthday earlier this year, I changed it to 1998, to give it more of a special feeling. 1998 being the year I was born.
Anyway, ever since then, I've been known as JeriKane or simply Jeri. So I was all like "Ahh.... Why not?" and I went with the same thing for my username on YouTube.
