"It's motherfucking Christmas! I'm the Grinch, motherfucker!"

While her album is in the works, Claire Boucher, better known as Grimes, teamed up with her step-brother Jay Worthy to put out this toe-tapper of a rather inappropriate Christmas song: "Christmas Song II (grinch)". And it's pretty perfect. She writes on Tumblr:

me and my step bro jay worthy make an annual christmas song with our siblings in order to avoid obligatory dinner. this is NOT a single from the upcoming album, not a serious piece of art in any capacity and not an official grimes release

also ‚ÄĒmade this song in prob less than 2 hours so please excuse my terrible production, + it is not mixed or mastered.

What an adorable family tradition. And damn what a great song to put together in a hurry.
