This song, regardless of its initial inspiration of Alien, is about rough sex, or at the very least, the mixture of pain and pleasure of a relationship. The idea is that these moments which are a mix of good and bad are more real and authentic than other banal moments. Screaming, crying...these things are "momentary", transient, but we still want these moments to reach an authentic intimacy with someone.
