It's a reference to Super Nintendo and protects my identity more than my last account name, plus the "SFA colors" Superman symbol tee, which I bought at the Student Center Barnes & Nobles on clearance and is now my profile picture, fits the name perfectly.
So there ya go.
My mom tells me I look like Clark Kent with my glasses on, and several former coworkers told me I had the Superman hair curl when it was longer.
Look, shut up, I love my mom, ok? Leave me alone guys. I'm gonna go fulfill some more nerd stereotypes now.
But seriously, I'm awesome and I deserve this name change.
Thank you.
nothing wrong with loving your mom. I love my mom. 
Haha.
I bet your mom loves you too! Loser!
L7 Weenie!
LOL.
Nothing wrong with what you like, and it doesn't matter what anyone thinks.
Damn straight. Next step: Super Sex Change! My mom doesn't like that idea, but I do, dammit!
Lol!
Hey I say to each there own lol!!!
I like it. Plus its better than the other more obvious play on words, Dub Step.lol
That's not an alliteration and I don't like most dubstep music I've heard, so that ain't about to happen. lol
Yeah, not a fan either.lol
i've always been all about anything that has Super in the name. Good change!
Now I need and X at the end with the exponent 64.
Hi Super Step. What kind of super powers do you got? What's your epic origin story?
Too bad you didn't call yourself Super Joe. Then you could be like that army guy in Capcom's Commando.
Maybe I should be Super Cary. But I don't know what my super powers would be. What do you think?
I think I put some of that stuff in my updated profile info, which I modeled after the character info in the Street Fighter II Turbo manual. 
I don't know much about Commando, but I liked the alliteration from using the first part of my last name.
I'd say you'd have the ability to freeze time, so you could eat power pellets full of spinach, gain super strength, and go ghost hunting. Also, healing abilities.
If I could freeze time, I don't think I'd eat power pellets full of spinach. I'd be tempted to take extra naps and play more video games. Because while I do try hard to work out and lift weights and stay healthy, I can also be really lazy, too! Healing powers...yeah I could see that. If I were in an RPG, I'd probably end up being the White Mage.
Lol, well then options are all there.
Nothing wrong with loving your mother, Mr. T agrees:
LOL. I think I first saw that on either a Cinema Snob or Nostalgia Critic review.
So we can call you Clark right, but once the glasses come off we have no idea you and Super Step are the same guy.
Yes, but my last name is Grizwold and I need some fucking Tylenol. Hallelujiah and holy shit!
Well it's better than Dub Step. *oh snap*
Plus SNES Step just doesn't roll off the tongue.
Yeah, I dislike dubstep too.
