Fussy definition is quite hard to grasp. It refers to someone who is extremely picky and nitpicking. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to expectations and flawlessness. Their meticulousness can be regarded as praiseworthy, but it can also intensify extreme censure and unjustified dissatisfaction. Being persnickety is typically connected with exact focus on specifics but can also be seen as a form of pedantry.
