The art of finding a random group of carolers and joining them with an extremely annoying instrument (such as a vuvuzela or kazoo) and/or singing along way off the original key of the song.
Some carolers passed by my house the other day and I joined them by playing my facemelting "O Holy Night" kazoo solo. It was a successful carol trolling adventure.

You have no idea.
