Satanism
Members who belong to the Church of Satan sign letters and emails and conduct rituals with the word 'Shemhamforash', although their version of it is different and contains 72 names of demons, not names of angels or God.
The word "Shemhamforash" is spoken in Church of Satan rituals, often followed by "Hail Satan!", as outlined in The Satanic Bible by Anton Szandor LaVey.
