A song by the industrial metal group Nine Inch Nails, all credits to Trent Reznor.

TheThe video for Happiness In Slavery features performance artist Bob Flanagan ritualistically washing himself and removing all of his clothing before strapping himself into a machine that subsequently tortures, rapes and kills him. Meanwhile, Trent Reznor watches and screams the lyrics from behind a metal gate, which opens at the end of the video, leaving Trent to enter the room himself. The video was universally banned. All footage in the video was real, except for the final killing of Flanagan, as Flanagan often fought the pain of cystic fibrosis by inflicting malicious damage on his own body.

The song, released only on 12" promotional single and the EP "Fixed" (Otherwise known as Halo 5) was not however released on CD and does therefore not have its own Halo Number. Although promotional CD containing only the track as it appears on the Broken EP was released, this too had no Halo Number

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
