It was a cloudy day in Ponyville, a slight wind chill which ruffling the hair and feathers of any pony who happened to be outside. The sky was filled with grey which seemed to stretch as far as the eye could see in all directions, blocking out the sun. Two ponies, a unicorn and a pegasus, walked side-by-side through the streets, heading for the Ponyville Day Spa.
"Oh darling, this weather is simply dreadful," complained Rarity, sniffing at the dullness of everything around her.
"Yeah, yeah," Rainbow Dash said dismissively. "If you think this is bad, you should see what the Wonderbolts have to deal with when we're cleaning up this mess!" The pegasus raised her chin, still flapping her wings slowly alongside Rarity as they approached their destination.
"Is that right?" Rarity paused for a moment to inspect her recently done front hooves. "Yes, I suppose a pony such as yourself should be used to drab conditions. In fact, I wouldn't expect any less," she said.
"Yeah, that's ri--" Rainbow Dash jabbed a hoof in Rarity's direction as she took in what Rarity had said. "Hey, what are you trying to say!?"
The stylish unicorn looked over in surprise. "I was simply stating that I am a lady who can't stand these dreadfully boring days, whereas a... lower class pony like you should be used to it by now since you deal with it regularly," explained Rarity, brushing her mane back over her shoulders.
"Um, technically I'm a lady too, Rarity!" snapped Rainbow Dash, waving her hoof in the unicorn's face.
Rarity snorted. "Of course, Rainbow Dash. I mean, the sound of your voice and the way you behave say otherwise, but I suppose you are correct."
Rainbow Dash bit back a biting retort. They were supposed to be relaxing, not taking jabs at each other. "Whatever, Rarity! Can we just go to the spa?" she said, grudgingly turning her head away and focusing on the building in the distance.
"Of course," replied Rarity. "That's a wonderful idea, Rainbow Dash. However, since you are a Wonderbolt, could you perhaps clear the sky of those dark clouds before we go?"
"How about no! I'm a Wonderbolt, not a weather pony."
"Oh, aren't they basically the same thing anyway, darling? Now please Rainbow Dash, we don't have all day." Rarity looked at her expectantly, nodding at the clouds that she wanted cleared.
In that instant, the rainbow pegasus finally snapped. "Fuck you, Rarity! I'm not your slave!"
"You do NOT swear at me, Rainbow Trash! I refuse to be spoken to like that. None of this would have happened if you Wonderbolts did your jobs properly!" Rarity retorted. How dare Rainbow Dash use such uncouth language toward her?
"We're not fucking weather ponies, YOU SPOILED FUCKING WORTHLESS PURPLE SHITSTAIN! DO IT YOURSELF!" Rainbow Dash couldn't believe what she was hearing. Am I just a tool to her?
"Excuse me, go fuck yourself Rainbow Dash. How dare you speak to me that way? I have more talent in my right hoof than you do in your entire body," said Rarity, grinning smugly. She knew it was true. Her fashion designs were marveled all over Equestria, and designers came to her specifically for advice. Rainbow Dash on the other hand...
The unicorn's thoughts were interrupted by the sound of Rainbow Dash's scratchy voice. "Oh yeah, and what talent would that be? Giving easy hoofjobs to any stallion who catches your eye?"
Rarity gasped at the accusation. "You did not just say that, you feather-brained fucker! I am a lady with class."
"Oh yeah? And what are you going to do about it?" taunted Rainbow Dash. "Sew me a dress? You stupid ten bit whore!"
"And darling, what have you ever done?" retorted Rarity. "Make little rainbows in the sky that nopony gives a flying fuck about? Or cry over not feeling important enough when someone does your job better than you? Nopony has forgotten the Mare Do Well incident, you know."
Rainbow Dash screeched in rage. "You mother fucker! My rainbows are way cooler than any of your stupid dresses!"
"Indeed, if by cool you mean utterly pointless, uninspired, trashy, and basic. Oh dear, I suppose that's the best you can do though, isn't it Trash Dash?" Before she could say any more, Rainbow Dash had crashed into her side, sending both of them tumbling to the ground.
"DON'T CALL ME THAT, YOU DUMB BITCH!" screamed Rainbow Dash as she torn at Rarity's mane. "I'll fuck Sweetie Belle's ass harder than Big Mac fucked your mom!" Rarity's horn glowed as she attempted to levitate Rainbow Dash off of her, but the pegasus was already off, flying high above her in the sky. "Ha! You're no Twilight, don't even try it!" laughed Rainbow Dash, soaring lazily through the sky.
Rarity shot a bolt of magic at the unsuspecting pegasus, who screamed in pain as it made contact. She tried to flap her wings, but the magic had done something, and she crashed to the ground. Rainbow Dash moaned as she tried to stand. "I think I broke something," she mumbled, limping away.
"Where do you think you're going, you pathetic, fillyfooling, unfashionable waste of air?" asked Rarity, jabbing her hoof into the pegasus's side. "Go clear those clouds and I suppose I can forgive you for your mistakes." She pulled Rainbow Dash's mane roughly, causing the pegasus to scream in pain. "But never forget that you are low class trash," she whispered in her ear. "Understood, darling?"
Rainbow Dash glared up at her defiantly. "GO FUCK YOUR MOMMA YOU DICK SUCKING WHORE. I'LL NEVER FORGIVE YOU FOR THIS!" In a final burst of strength, she tore away from the fashionista and retreated to her house in Cloudsdale.
Later that day, Rainbow Dash told Princess Twilight about what had happened. When Twilight was finished hearing the story, she banished Rainbow Dash to Tartarus and gave Rarity Rainbow Dash's home as another fashion design base. Fillyfoolers are unacceptable, thought Twilight, rolling her eyes as Rainbow Dash's cries grew fainter and fainter as she fell into the abyss.
