What's that song that talks about killing santa?

There's this song that I heard on youtube a few years ago, and I wanted to know if anyone knew the name of it? It talks about killing santa claus, and the person singing sounds like a little girl's voice (I'm pretty sure, but not completely. Keep in mind that this was about 4 years ago). The only line from the song that I remember, is something like "... takes a peek inside...". And that's only one little bit of a line. The story line of the song, is a little girl and she's making plans with her friends to kill santa by leaving him a gift under the tree that has a bomb or something in it and when he opens it it basically blows up in his face. If you have any ideas of what this song may be, even if you're not completely sure about it, then please let me know.
