Fussy definition is quite elusive. It refers to someone who is exceptionally selective and judgmental. A persnickety individual tends to be fastidious and has high standards when it comes to criteria and excellence. Their fastidious nature can be seen as admirable, but it can also magnify overly demanding disapproval and avoidable dissatisfaction. Being persnickety is commonly linked to exact attention to detail but can also be seen as a manifestation of pedantry.
