Persnickety sense is somewhat elusive. It refers to someone who is extremely meticulous and judgmental. A persnickety individual often pay strict attention to detail and sets the bar high when it comes to expectations and excellence. Their fastidious nature can be seen as admirable, but it can also magnify extreme disapproval and unnecessary dissatisfaction. Being persnickety is frequently associated with detailed attention to detail but can also be seen as a form of pedantry.
