Ok, I have a really dumb question (I will prove that there is such a thing)

, what on Earth is an NSV? I have seen this thrown around on this board, but have no clue what it is!
I also have a hard time tooting my own horn, but I think that comes from years of low self image/esteem. As I'm even getting complements from others, I have a very hard time with what to say and it makes me so uncomfortable...but not as uncomfortable as I felt in the high end of my weight!
