Fire-breathing bosses are often referred to as OGRES, a mythical creature from European folklore. OGRES are typically depicted as large, brutish, and monstrous humanoids with a taste for human flesh. They are often characterized as having a voracious appetite, a short temper, and a tendency to breathe fire. In modern culture, the term 'OGRE' is often used to describe a person who is overly demanding or intimidating in their leadership style.
