FuckKnocker is a noun. It can be used as a term of endearment or another way to call someone an asshole or some other derogatory name.

Most recently, it is the term that I have coined for certain members of management who have gone out of their way to screw over my self and many of my peers.
My good friend Paul just told me that I could not take a trip to NY to visit a client. Hey Paul, why you being such a FuckKnocker?

Our Senior VP in charge of marketing just terminated 25 jobs from the group but will still keep his own (and get a raise). Hey Kevin, your a giant FuckKnocker!
