Relating to, characteristic of, or resembling Beelzebub; devilish, demonic, or associated with evil or wickedness.
From Beelzebub (Hebrew 'Ba'al Zebûb') plus the suffix '-ian,' which creates adjectives from nouns. The term appeared in religious and literary contexts, especially during the Middle Ages and Renaissance.
Medieval and Renaissance authors loved creating '-ian' adjectives to describe moral qualities—calling something 'Beelzebubian' was a way to invoke the entire concept of demonic evil in a single, damning word!
