Slayer.net The Official Slayer Site: News, Photos, Music and More
Excerpted from the website:
- The band was originally known as Dragonslayer before shortening its name to Slayer. Contrary to what some believe, the name was not chosen as an acronym for Satan Laughs As You Eternally Rot; rather, this wording, found on the liner notes to Divine Intervention, was added as a backronym after the name was shortened. Araya has jokingly stated that they chose Slayer because "it was cool, easy to chant".  The backronym might orginate from the line "Laughing as you eternally rot" from the song "Live Undead" (South of Heaven, 1988).
