Term for a person enamored with Greek history and culture, particularly those of the late-antiquity and medieval periods. Often a byzaboo is not actually Greek, but constantly touts their nationalistic views on the internet. The word comes from the Byzantine Empire, which was the Greek/eastern continuation of the Roman Empire and lasted until 1453 A.D. Originates with /gsg/ - "Grand Strategy General" on 4chan's Video Games board.
A playful nickname to call your s/o when you both find calling eachother 'babe' cringe worthy, a comfortable middle between loving and over the top. The nickname 'baby' rearranged.
