Fussy sense is fairly difficult to understand. It refers to someone who is exceedingly choosy and critical. A persnickety individual tends to be fastidious and sets the bar high when it comes to standards and excellence. Their meticulousness can be viewed as laudable, but it can also magnify overly demanding censure and superfluous dissatisfaction. Being persnickety is frequently related to detailed attention to detail but can also be seen as a type of perfectionism.
