NAGD meaning in Internet ?

Nagging, in interpersonal communication, is repetitious behaviour in the form of pestering, hectoring, harassing, or otherwise continuously urging an individual to complete previously discussed requests or act on advice. The word is derived from the Scandinavian nagga, which means "to gnaw".

Reporter Elizabeth Bernstein defined, in a Wall Street Journal article, nagging as "the interaction in which one person repeatedly makes a request, the other person repeatedly ignores it and both become increasingly annoyed". Thus, nagging is a form of persistent persuasion that is more repetitive than aggressive and it is an interaction to which each party contributes.

Nagging is a very common form of persuasion used in all aspects of life including domestic and professional. It is also a common practice in order to avoid more aggressive persuasive moves like threats.
