prissiness
noun
The state or quality of being excessively prim or proper.
Examples:
"The first lesson: that however much I might like to say that I was being prissy about it because I wanted to Avoid Being Pedantic, or that, yes, my reluctance to use the term was pure prissiness but that my prissiness is not a function of Bigger Issues, neither of these statements is truthful." -- The Vagina Dialogues | Her Bad Mother 2006
