Short for "Not Mind Safe" (and not for "Not My Style", what kind of lame "street" phrase is that anyway). Indicates content that so disturbing it should be forever left unseen. Used as an extreme warning for images whose full horror is not covered by NWS (Not Work Safe).

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.
