Here's the breakdown:
* Billie Jean: The song title is a fictional character who claims to be Michael Jackson's love child.
* Spell: The word "spell" can refer to a magical incantation, but in this context, it likely means to write out the letters of a word.
Therefore, the phrase "Billie, will you spell me?" can be interpreted as a playful request for someone named Billie to write out the letters of the word "me". It's a humorous way to reference the song and create a lighthearted interaction.
