How did Slayer get their name?

Slayer was formed in 1981 by guitarists Kerry King and Jeff Hanneman, bassist and vocalist Tom Araya, and drummer Dave Lombardo. The group began by playing cover songs by bands such as Iron Maiden and Judas Priest at parties and clubs in Southern California. The bands early image relied heavily on Satanic themes that featured pentagrams, make-up, spikes, and inverted crosses. Rumors that the band was originally known as Dragonslayer, after the 1981 movie of the same name, were denied by King, as he later stated: "We never were; it's a myth to this day."
