B.B.B.F.F.

B.B.B.F.F, which stands for Big Brother, Best Friend Forever, is a song that features in the episode A Canterlot Wedding - Part 1. Twilight Sparkle first sings it when she explains to her friends that Shining Armor was the only pony she trusted as a friend before she was sent to Ponyville. Later in the episode (when she was afraid she had 'lost a brother'), she sings a somber, much shorter reprise.

Lyrics

 * [Twilight Sparkle]
 * When I was just a filly I found it rather silly
 * To see how many other ponies I could meet
 * I had my books to read, didn't know that I would ever need
 * Other ponies to make my life complete


 * But there was one colt that I cared for
 * I knew he would be there for me


 * My big brother, best friend forever
 * Like two peas in a pod, we did everything together


 * He taught me how to fly a kite
 * (Best friend forever)
 * We never had a single fight
 * (We did everything together)
 * We shared our hopes, we shared our dreams
 * I miss him more than I realized, it seems


 * [Rest of main six]
 * Your big brother, best friend forever
 * Like two peas in a pod, you did everything together


 * [Twilight Sparkle]
 * And though he's oh so far away
 * I hoped that he would stay
 * My big brother best friend
 * Forever
 * Forever

 * [Twilight Sparkle]
 * He was my Big Brother, Best Friend
 * Forever,
 * And now, we'll never do anything
 * Together...
