Prigs are people who are overly concerned with propriety and etiquette, often to the point of being judgmental or hypocritical. The term 'BLUENOSES' is a slang term for prigs, referring to their tendency to be overly moralistic and strict. Fusspots are also prigs, as they are overly concerned with details and rules, often to the point of being annoying. Prudes are similar to prigs, as they are overly concerned with propriety and modesty, but they tend to be more extreme in their views.
