Another word for anal sex, according to Andrew Biersack and Matt Good.
Matt Good: You know, getting buttfucked wouldn't be that bad for getting a bat belt. It's like ten minutes of weird pain.. like backwards poop.. and then.. and then you have a sweet bat belt forever you can climb buildings, you can throw grenades at people..
Andrew Biersack: Is getting buttfucked like backwards poop? Write it. Matt Good thinks being buttfucked is like a reverse poopjob.
