"Fastidious" describes someone who is extremely attentive to detail and cleanliness, often to an excessive degree. Think of Monica Geller from "Friends" and her obsessive cleaning habits. It's not just about being tidy; it's about demanding perfection. Someone who is fastidious might meticulously organize their closet by color and style, or constantly correct minor imperfections. It often implies a critical and exacting nature. It can be both a positive and negative trait.
