An "egomaniac" is someone who has an excessive and obsessive sense of self-importance. They are extremely self-centered, arrogant, and often believe they are superior to others. Think of them as egoists on steroids. Their inflated ego dominates their thoughts and behaviors. They crave attention and admiration and may be oblivious to the needs and feelings of others. It's like someone who thinks they're the star of their own movie, all the time.
