“I dares you to step outside and let your precious, tidy hair get ruined again.” -Applejack
“Okay. I dare Applejack to play dress-up in a frou-frou, glittery, lacey outfit.” - Rarity

When a major scheduled storm hits Ponyville, Rarity and Applejack get caught out in it when Twilight comes to the rescue and invites them to stay the night. They are both grateful to to Twilight for helping them out of the storm (why Applejack a water creature is bothered by the rrain is anyone’s guess).

Taking advance of the situation Twilight turns the night into her first ever slumber party. They start to play games with Rarity and Applejack arguing the whole time. When it comes time for Truth or Dare they both take advance of the game to make the other one suffer.
