eljoemo is one of my 3 online nicknames, and the one with the most interesting story behind it. The other 2 (ninja of lemons - my ign and Xbox live name at some point - and Tactical Squid - minecraft and CW) are just chosen because they sound awesome. But eljoemo actually has a better reason behind it.
I first used eljoemo when I registered for my Kongregate account 5 years ago, making me 11 at the time. Around then, and still kinda today, I was a pretty big Simpsons fan (it is pretty hilarious). For those who don't know, the son Bart has the sort of graffiti/ street name El Barto. I thought it was pretty awesome and so applied it my name, turning Joe (or Joseph) into eljoemo (sometimes El Joemo if I feel like it). It's the name I've used the most, I've used all 3 randomly for social online accounts.
