What do YOU think Spitfire's nickname is?

In today’s episode we found out that every Wonderbolt has a (Sometimes offensive) nickname, and we have heard all of them…except for Spitfire, which is never mentioned.
 
So, what do you guys think Spitfire’s nickname is? My personal bet’s on “Bitchfire”; reasons should be pretty obvious ;)

@DragonBoi471  

What, not “Shitfire”? :P

I’ve got one; “Fartfire”. …Yeah, I guess I’m immature. XD

@DragonBoi471  

Offensive? Soarin’s comes from accidentally clipping a flagpole, Fleetfoot’s was from accidentally landing on Spitfire’s hoof, Surprise’s is “slowpoke”… for the most part, it seems like all the nicknames are for simple goofs and minor accidents they had when they themselves were new to the team. Heck, it may even be a way of bonding with them. Nothing brings people together like knowing we all make mistakes, after all, and they’re pretty open about theirs when asked.
 
Still, if I had to guess… how about flameout?

How about clitfire.

Let’s not forget, Misty Fly was nicknamed “Dizzy” and High Winds was nicknamed “Hoof-in-Mouth”. The latter of which can lead to the imagination.

Private Pile (of shit)

Diaper Genie sounds cute! :D

Something with swearing in it, hence the whisper.
 
Shitfire is the obvious one. Maybe she had an accident with raw sewage on her first day.

Spitroast! :D
 
Cmon, there’s a reason we couldn’t hear it as viewers. :P

trash fire

@Poison Trail  
Second this, she had a very awkward first day…

Shitflier, she crapped herself midair day one.

@Background Pony #A774  
You just made the joke because you hated the episode, didn’t you?

ShitFire, obviously

Backfire  
Slowcoach  
Horse-spit  
Dumpy  
Flipper  
No-Hooves  
Gilda

I’m very certain that it’s not Shitfire. They wouldn’t make that kind of joke. It also sounds to mean-spirited compared to stuff like Flatfoot or Clipper.
 
So maybe something with spitting?

Splitfire

It has to be “Shitfire.”

( ͡° ͜ʖ ͡°) Dickfire

I think her nickname was something along the lines of “clopfire” because she was caught clopping in the locker room on her first day.

Could do with spoiler tags on that ;)

What do you mean? There are spoiler tags. The image uses Derpibooru’s tagging system so your filters will hide it if you have them set to hide or spoiler it
