What is the name of this song?

There is a song that I found once but I cannot remember the title of it. It was by Bring Me The Horizon, and it's one of their deathcore songs although it is not listed on either of their deathcore albums. I would look the lyrics up but I cannot understand any of them, except once in the middle of the song the words "Just f-kin' relax, aye," are said in a weird voice. It is really starting to annoy me because I can't find it anywhere online. Help? Thank you! :)
