The best friend thing is BS. Just has to be someone close to you (Ex: Kakashi/Obito losing Rin).
We are not told however.
Perhaps his pet frog died.

Because He Watched Too Much Porn And Hentai xd
No, there are ways to unlock the MS besides killing your best friend....Itachi was only trying to push Sasuke in to gaining the MS powers so he could fight him and die and Itachi didn't give Sasuke his MS powers because if that was the case then Sasuke should also have the same MS design as Itachi and should have a God-like Tsukuyomi at Itachi's level, but that's not the case.
An Uchiha can unlock their MS 2 ways
1.Either throw killing a best friend.
2.Losing a love one which is Sasuke's case when he lost Itachi.
id say its the 2nd the best friend thinf is that of the 2nd cause your best friend will be the closest on to you

No, your best friend is the closest person to you outside of your family, but your family are your true love ones....that why Sasuke unlocked the MS when Itachi died since he saw Itachi as his closest person in the world.

And Obito unlocked his MS after seeing the death of the girl he loved soooo.... your theory is flawed sir/ma'am.
