Hail Satan

Hail Satan, sometimes Latinized as Ave Satanas or Ave Satana, is an exclamation used by some Satanists to invoke the name of Satan in contexts ranging from sincere expression to comedy or satire. The Satanic Temple uses the phrase as a sincere expression of rational inquiry removed from supernaturalism and archaic tradition-based superstitions.

Believers in backmasking think they can hear "Hail Satan" and other similar messages in some songs played in reverse, such as "Walk This Way" by Aerosmith. The grammatically questionable variation Ave Satani is sometimes used, based on the title by Jerry Goldsmith in his theme music to The Omen.
