Troll the Ancient Yuletide, Carol?

Or is it Troll: the Ancient Yuletide Carol? It's become nearly impossible to decipher the author's intent.  But every good literary student knows that the author's original intent doesn't matter because the work takes on a life of its own as soon as it has left the author's pen.  

As with other words (like "Christmas"), the meaning is open to personal interpretation; the line of this song can mean whatever you want it to mean.  In fact, the meaning is so vague, high school students have been at liberty to argue the finer points of this debate through written essays.  

At the end of the day, one of these many opinions will be declared the winner, the meaning magically universally agreed upon.  That is, until the sands of time again erase its meaning.
