NSS

Noun. An abbreviation for the medical term: Nasoom Sleepless Syndrome. This term is considered to be out of date by many experts in the field and hence has lost its place in the modern medical texts.

Doctor: I'm afraid your symptoms are consistent with NSS, or Nasoom Sleepless Syndrome. I will prescribe you some Ambien, it should help you regain your normal sleep pattern.
