Demanding definition is quite difficult to understand. It refers to someone who
is exceptionally particular and disapproving. A persnickety individual typically nitpick and sets the bar high when it comes to criteria and flawlessness.

Being persnickety is often linked to exact attention to detail but can also be seen as a type of perfectionism.
