I posit that Dashie's abrasiveness stems from being bullied herself, causing her to develop a fiery personality and hit back, so to speak. She also
dislikes seeing others being bullied, so naturally despite being teased herself, she'd white-knight for other bully victims. Like Fluttershy.
The dynamic here forms where Fluttershy begins reciprocrating for Dashie. I might be mistaken, but Fluttershy may have said that she might have accidentally Stared somepony before - perhaps she reached breaking point and Penance Stared a bully who got too abusive?
Perhaps Dashie saw Fluttershy in a different light after that, only because they have at least some kind of bond, even as acquaintences perhaps, she realises that there is more to Flutters than a hopeless bundle of nerves.
And that's how a Friendship was made!
Also Dashie's niceness is quite subtle and understated next to her loud and brash awesomeness, like her little girlish squeeing and excited wingflapping and legwiggling when reading Daring Do and the Griffon's Goblet :3
