Cupcakes occupies an interesting space in the My Little Pony: Friendship Is Magic lexicon, in that despite its reportedly 'written on a whim' status, it can justifiably be called the most infamous fan fiction of the Friendship Is Magic fandom (Or simply, brony community), or even of all time. It has become so ingrained in the considerably vast FIM fandom that one will miss a boatload of references and jokes throughout the fandom if they have not, themselves, taken the plunge and read Cupcakes. It IS Cupcakes, and it doesn't seem like anything is going to change that any time soon.
