This idea came randomly to my mind more than half a year ago. I remember it was between December and January.
Fashionistas are having runs
“Rarity, Sassy Saddles and Coco Pommel were invited to Fleur Dis Lee’s house to have a taste of special dish she prepared for them. It was chili con carne. They were very excited to taste it so all four of them had a nice lunch at Fleur’s place. They all agreed it tasted good. 30 minutes later after they finished eating they decided to go to the Canterlot Mall for a shopping. But once they reached the Mall and went inside they felt butterflies in their stomachs. All four of them. So without any hesitation they dashed to the nearest public restroom though I wouldn’t call it dashed since they had to clench their buttcheeks. Once they found a restroom and realized it was completely empty they dashed to the stalls, locked the doors, pulled their panties/shorts down, placed their asses on toilet seats and let out large chunks of nasty and intoxicating diarrhea into the bowls. Let’s hope no one will enter while they’re dealing with it since they all were quite noisy. Hearing and/or smelling it would be very embarrasing for them.”
