Bookah

General
"Bookah" is a Asuran phrase that is used to refer to all non-Asuran creatures, and not, as some suspect, specifically to Humans. It typically denotes inferiority, and is often used in a condescending manner. It is also the name of loud, bellowing, make-believe monsters that Asura parents created to scare children.
