could be in two ways both twisted
1) the very first lie- everybody lied to their significant other at least once and he wants to do it and it matters to her that he is lying
2) EVERY LINE IN THE SONG IS WHAT A BOY SAY TO A GIRL HE'S BEEN DATING TO GET HER IN THE SACK...this is what i think the song is all about, just the irony of it, everything so sweet but yet wanting to tell a lie
