Someone who takes nr = nt literally and close to heart. These people have no respect for the complexities of other people's lives and assume that everyone is around to answer instantly.

However, this is not to be confused with someone who is impatient, as an impatient person will be annoyed but not distinguish your answer by your delay.

Licata 2: Good thing you smashed her sister.....Nernetter bitch ass gonna learn her lesson.
