Choosy sense is quite elusive. It refers to someone who is immensely choosy and judgmental. A persnickety individual tends to nitpick and has high standards when it comes
to quality and excellence. Their attention to detail can be viewed as laudable, but it can also intensify unreasonable disapproval and unjustified dissatisfaction. Being persnickety is commonly associated with detailed focus on specifics but can also be seen as a manifestation of obsessiveness.
