I was coming up with ideas for what I was going to name my YouTube channel in the future when I was in 5th grade. I was originally going to name it DrRBXYMS (Lord knows what the hell all of those letters stood for) but then I thought that maybe it'd be a better idea to name myself something that fit my personality instead.
Eventually I decided to name myself TheAngryNerd, because it describes me very accurately. I used to ragequit in video games a lot and I was a huge nerd, and I still am. But at the time, I loved DrRBXYMS so much that I combined them into a monstrosity: DrRBXYMSTheAngryNerd. Also, I started watching AVGN a little while before this (He's the entire reason I wanted to make a channel in the first place lol, huge inspiration), and TheAngryNerd was way too similar to TheAngryVideoGameNerd so I just rolled with that horrible username for a while.
Around two years later in 7th grade, I found out that my school deleted my channel because I made it using my school account. Since I turned 13 later in the schoolyear, I decided to make a gmail account and make a new channel. I decided to finally let go of the DrRBXYMS and just be TheAngryNerd. It's been my username everywhere ever since... except that in some sites, the username was already taken, so I had to use something else. The end result was TheAngryNerd101. Why 101? Well it sounds kinda cool and has a nice feel to it and is a pleasant number to look at.
