Joe Hottinger records riffs on his phone, then names them something so he can figure out what's what. The Halestorm guitarist recalled to Louder Sound
that he came up with this tune upstairs at home "with a bunch of dumb rock'n'roll skull things laying around, and I thought, 'Skulls! That will do!'"
He played the riff to Halestorm frontwoman Lzzy Hale, who was immediately inspired and started writing melodies and lyrics. They ended up with "lines about not being just another empty skull, and not being a dummy."
