The act of sending short, usually single line, e-mails to people to get them to react to some issue. Particularly common today with hand held devices and continuous time connectivity. Used by many to exert power over others and to reduce productivity. The victims usually are forced to respond with an e-mail 4 to 5 times longer in order to clarify the issue to prevent further e-nagging. Also know as e-nudzhing (Yiddish).
Sorry I'm late, but my boss was e-nagging me, so I had spend the next hour writing an e-mail explaining how Excel worked.
Nagging rights are a privelage inadvertantly granted to a girl at the beginning of a relationship. It generally refers to a gentleman's obligation to put up with ridiculous demands and constant irritation (which he would never do under normal circumastances) from a female partner for the good of the relationship.
Somehow, many women manage to retain nagging rights even after a breakup, especially in the case of divorce.
