You're My Better Best Friend

Lyrics
Today I've learned a lesson, What a best friend should do. I put busting my brothers Ahead of you. You were always there for me, On you I could depend. And now, too late, I realize I should've been a better best friend! (Ooh-wow-wow-wow-wow)

I said things I shouldn't have, Did things I shouldn't do. Guess I forgot that you cannot Spell Us without "U." (Oooh-wow-wow-wow-wow)
