Term used to describe a girl who is just plain NASTY but not in the "infested with diseases type" nasty... just viciously NASTY! Often, people have lovingly applied such letters as an initial for someone who is Nasty as in Nasty McNasty... or Nancy McNasty!
Daamnn... did you hear what that NMN just said?? That was just straight-up NASTY that I can't even reiterate what she just said!
