After watching the music video with the juxtaposition of animal carcasses and young couple, I think the lyrics' repetition of 'hearts', pulsing blood and 'forcing it into us' refer to both the adrenaline and blood rush of an intimate relationship and the slaughtering of animals. The dead animals in the Butcher shop demonstrate how we consume and force this now cold blooded animal into our systems, which keeps our blood pumping and our hearts pulsing.
