Rarity 

A bad-ass fucking pony from My Little Pony: Friendship is Magic. She'll make a dress faster than you, and whine about how you take long to do it. And laugh in your face like this. "BwaHA-HA!"

Guy 1: "Dude, Rarity was awesome in that last episode!"
Guy 2: "I thought Fluttershy was pretty cool in it too."
Guy 1: "LOL"

Rarity 

A fucking pony goddess. Rarity is the fashionista of the show 'My Little Pony: Friendship is Magic'. Rarity's element may be generosity, but that is only a short word in a long list of many. She is kind, generous, fashionable, loving, loyal, and a great singer. She lives for her friends and her fashion. In short, if you ever meet a Rarity, consider yourself lucky.

Pinkie Pie: Oh my Celestia, Rarity is so cool, and sooo nice.
Spike: I know. 😍

Dinosaur rarity 

Something so uncommon or unheard of, it's as rare as the dinosaurs.

"I do not like waking up early unless I awaken on my own and feel great, then I love it. But that is a dinosaur rarity".
