Me and my buddy used to watch a lot of cod videos on youtube. We watched one particular player named MisterFantasmo often. MisterFantasmo had a friend he would feature on his channel known as Kid Lazer.
In one of our classes we were supposed to get into partners/groups to create these stupid interview skits. Me and my buddy partnered up and then proceeded to do nothing. When the time to present the skits came around, we just improvised. He was my interviewer "Mister Fantasmo" and I was the interviewee "The Kid Lazer". Shenanigans ensued. Our teacher stopped us in the middle even though our presentation was like one of the only two that had a positive reaction from the class. The rest were boring as shit. Tsk.
After that a bunch of people started calling me The Kid Lazer. It was funny to me, I liked it, it stuck. I've only used it for like 2 different games including MC though.
