In the song Justin kept saying, "what do you mean?" I mean like seriously. Here is an example.
Fan: I love you Justin Bieber!!!!
JB: What do you mean?
Fan: I love you as a fan* blush*
JB: What do you mean?
Fan: Ugh. Never mind!
JB: What do you mean?To all JB fans I'm sorry if its too sensitive. I mean no harm to Justin. I myself like him too.
