Fussy definition is rather elusive. It refers to someone who is immensely choosy and fault-finding. A persnickety individual usually be fastidious
and has high standards when it comes to expectations and perfection. Their attention to detail can be viewed as laudable, but it can also exacerbate excessive censure
and superfluous dissatisfaction. Being persnickety is commonly associated with precise focus on specifics but can also be seen as a form of obsessiveness.
