nm 

An abbreviation of "not much" or "nothing much". It is most commonly used in instant messaging conversations as an easy and thoughtless answer to the question what's up.

Some people also use it as an abbreviation for "nevermind", but "nvm" is more popular.

Typical start of an MSN conversation:
Jack: hey
Jill: hey
Jack: sup?
Jill: nm u?
Jack: nm
Jill: cool
Jack: yup
Jack: (starts talking about something)

nm 

an annoying/lazy way of saying "Oh, I was just sitting here with my thumb up my ass, waiting for you to ask me what I was doing. In fact, let's just stand here and piss away 3 minutes of our lives talking in unclear ambiguous terms about how our day is, what we did five minutes ago, and what we plan on doing five minutes from now."

Person 1: Whazzzz up??
Person 2: nm
