The term 'stuck-up one' is often used to describe someone who is arrogant and thinks they are better than others. This term can be described by three words: SNOB (4 letters), SNOOT (5 letters), and PRIG (4 letters). A SNOB is someone who looks down on those who are not of the same social class or have the same interests as them. A SNOOT is someone who is very particular about their behavior and appearance, and a PRIG is someone who is overly concerned with propriety and etiquette. All three words describe someone who is stuck-up and believes they are superior to others.
