Choosy definition is somewhat difficult to understand. It refers to someone who is immensely meticulous and fault-finding. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to standards and excellence. Their fastidious nature can be viewed as laudable, but it can also lead
to excessive criticism and unjustified dissatisfaction. Being persnickety is commonly associated with thorough focus on specifics but can also be seen as a manifestation of perfectionism.
