This was originally done as an instrumental, before the band added random lyrics. Kim Gordon recalled in her 2015 memoir Girl In a Band: "All of us. I remember, wrote down lines on a piece of paper, and when it came time to overdub the vocal, I randomly cherry-picked from the list. It's a way of working. I sometimes still use."
"We told the sound engineer we wanted a big bass sound, like Johnny Rotten's post Sex Pistols band, Public Image Ltd. I whispered my vocals and Lee Ranaldo added his own vocal accompaniment."
The song "Sadeness" by Enigma (the one with the chanting monks), got its name from the French novelist Marquis de Sade, who believed sex had to be painful in order to be pleasurable - thus the word "sadism."
