NM 

Probably the most annoying excuse of a word ever invented. Used mostly in Instant messengers and text messaging it is a way for the other person to show you that they could give a shit about what you think/do/exist etc... it stands for "nothing much" and should never be used by any man or woman. and if used tell them they are a fag and should go kill themselves.

Bob: yooo.
Fred: Eyy whats good kid?
Bob: nm.
Fred: Your such a fag man you should go kill yourself.

Quite possibly the most annoying "Word" knows to the "English speaking nation." shortened, or "1137" way of saying "Not Much."
Its just that our time has gotten to lazy to type nothing much, which is stupid because if your not doing anything you should be able to type "Nothing much".

Me;Hey
loser;hi
me;Whats Up?
loser;nm
Me;Why don't you just type nothing much you loser.
