This MCR x Mariah Carey xmas song mash-up will make you spew

In what we can only describe as "fucking horrible", someone out there with way too much time on their hands has mashed-up  My Chemical Romance's 2007 hit 'Welcome to the Black Parade' with Mariah Carey's 'All I Want For Christmas is You'.

The worst part? You'll find yourself tapping away getting caught up in how annoyingly catchy it is. So we reccommend not watching it.

If you can last all the way to the end, you're a better man than us.
