0 an annoying or boring person, especially someone who is always criticizing or complaining:
He earned himself the reputation of being a nudnik and a pedant.
What makes him such a nudnik, such a pest?
Melvin, you are such a nudnik!
He is painted as a nudnik simply because he's into golf and finance.
He plays a grandiose, macho nudnik with a raging ego and a hair-raising sense of grievance.
