Person 2: Rainbow Dash? Sounds pretty stupid and gay. Like you! ohhhhhhhhHh!!!
Person 1: Dont be rippin' on RD, she will fuck you up.
However, she is not without her character flaws, she has a temper that may cause her to try and attack an antagonist who was being a jerk. Can be insensitive and arrogant. Even though the arrogance was down a notch after The Mysterious Mare Do Well, she still does have some. Not to mention she is quite brash.
But despite that, she never leaves her friends hanging, and cannot abandon them for her own heart's desire.
Brony: NO, I mean the TOMBOYISH 2010-Now pegasus who can break the LIGHT SPECTRUM!
Non Brony: Uh...
And you just got 20% cooler in the 10 seconds flat that you read this.

Boy: Fluttershy and Rarity
Girl: That's a shame
Girl: RainbowDash is about 20% cooler
She is a light blue earth pony with a pink, orange, yellow, and green mane and a pink, blue, and purple tail. She features a cutie mark of a rainbow stretching between two clouds. In 2009, during My Little Pony's "Generation 3.5" mass redesign, she was shown with a large ponytail in her mane.
Rainbow Dash is described as stylish and fashionable. My Little Pony calls her "The Glamour Girl of Ponyville." She is a kindhearted pony and is very interested in fashion and she also has a tendency to use say the word 'Darling' very often.
Note: Nothing is wrong here. I am aware that as of 2010 she was redesigned as an athletic pony. It isn't right, however, that all the definitions of her leave out this chunk of history, so I wanted there to be a definition on THIS Rainbow Dash as well. Though a lot of people will be tempted to downvote this because it's a side of the character you don't like, It's important that this be defined as well.
