On the mispronounciation thing, can everyone please remember it was initially Tsuna not wanting to be called Vongola Decimo? Some of the pronounciations are fun, other- somewhere it got abbreviated to VD, and my first default with anacronyms is Medical. So I bet Tsuna would quit mispronouncing as soon as Reborn or Shamal started calling Tsuna the 'Venereal Disease'.
Naw i doubt it. Tsuna doesnt associate vongona deook with his identity, so he probably uses that name too
