"Iä" is a word used to address eldritch Lovecraftian gods of supreme cosmic evil. Probably the (currently) most common use of this greeting is "Iä! Iä! Cthulhu fhtagn!" Which basically translates to "Hail! Hail! Cthulhu sleeps!" "Iä!" is pronounced thusly: ee-AY! (same phoenetic vowel combination as "eat cake.") This word can also be used to describe something suitably badass, or perhaps evil in a hokey sort of way. It's quite versatile.
