N.H.K is a term coined by the Japanese animation titled "Welcome to the N.H.K" the term is usually used to define a series of negative scenarios that will drive a person to do things completely out of their character. It has been defined as god or an evil organisation bent on ruining peoples lives for no given reason. The N.H.K can differ from person to person and is in some situations completely situational.

Get the N.H.K mug.
The name of a very interesting light novel, manga and anime series created by Tatsuhiko Takimoto about Tatsuhiro Satou, a hikikomori, or shut in, who abuses drugs and looks at porn. There are a bunch of other characters with their own problems. A great franchise to get into.
That guy over there reminds me of Yamazaki from Welcome to the N.H.K. because he looks at child pornography.

Nihon Hikikomori Kyōkai or Japan Withdrawal Association
NHK is an organization that sells anime-related products in hopes to create Otaku that are shunned from society. Its goal is to create shut-ins. They tend to create multiple situations that lead to one being barraged by multiple misfortunes. They are seen as a one percent true conspiracy. They are the Illuminati of anime.
The NHK or N.H.K. are the reason that my life is in shambles! I will not let the NHK destroy my life!
