Cupcakes, actually.

Free pie?

Bitch please, Pinkie loved the name.
 
You know what happens to folks who don’t like what Pinkie likes.

No argument with you there from me OP.

I don’t mind it, but it sounds more like a parody of an MLP name more than an actual one.

Even by pony standard, it’s pretty silly.

I like calling her fizzy. That could have been her personality back in her day.
 
Rumor has it real horses with softer names are more desirable as horses with harder names implies they’re cowards.

Well, I admit I didn’t know that about good Steven.
 
But I want to make a point.

She can go into education and tell her students to call her Ms. Fizzle.

I guarantee you it was chosen specifically because it sounded so silly. That was the point. You have this malicious, evil character with an aggressive name who, at the end, reveals her real name as being completely opposite of what you’d expect. Kind of like a tough, gruff biker who goes by “Butch” turning out to really be named Marvin or something.

Steven Magnet was a fan name that became canonized, like Lyra and Octavia (see note on those below.) It was the result of YouTube’s crappy captioning system. Someone noticed instead of “sea serpent” it captioned the line as “Steven Magnet”, and a meme was born. The fandom adopted it as his name, since he didn’t have one anyway (the writers later said he was just “sea serpent” in the script) and Hasbro decided to trademark it and use it.
 
In the case of Lyra, her original name as used in the toys only was Heartstrings. The name “Lyra” had been used by fans since long before that. To reconcile the difference, fans suggested that “Heartstrings” was really her last name. Hasbro went with this, and made it official. For Octavia there was no existing name, so they just slapped “Melody” on it to make it trademarkable.

Not the most stupid name, but definitely very silly for an evil action oriented second-in-command of an army.
 
Then again Equestria have a knack for putting weird names to their citizens like “Sweetie Drops”, “Flurry Heart”, “Fluttershy”, “Sweetie Belle”, “Apple Rose”, “Moon Dancer”.
 
And we also have ridiculous names like “Filthy Rich”, “Spoiled Milk” (Diamond Tiara dodged a bullet here).
 
As weird as equestrian names can be, yeah, it’s not an excuse thought when we also have names like “Steven Magnet”, “Shining Armor”, “Photo Finish”, “Daring Do”, “Sunset Shimmer”, “Sapphire Shores” and “Amethyst Star” to name a few, heck the wonderbolts themselves are a bunch of ponies with cool names.
 
At the very least a normal name like “Trixie”, “Gilda”, “Ember”, “Suri” could have sounded less silly. Thought despite everything Fizzlepop Berrytwist have some charm anyway.
 

 
Man I don’t know how pony names work.

I just call her Fizz

@wumbl3  
Same here. It’s cute. Then again, so are most of the Equestrian names in their own rights.

I for one love her real name.

Not like any other name in Equestria is any better or less silly.
