Or when you're feeling too kind to call someone a dick but they deserve to be called something harsher than a dork.
Derived from the work doi. (the essence of everything)
It is the place in question you are or where somebody else is.
It can also be the object that is in use by someone or the object desired by someone.
Joel: Actually, I'm already having people over to my doik tonight so YOU come to MY doik!
Also, in the context of an object:
"Pass me that doik!" - of you are holding a pen than you know that pen has been replaced with the noun doik.
Max: "Oh, you...you...doik!"
Doug: "What! What's a doik?"
Max: "If you must know, I made it up as a horrible epithet!"
Max: "I'm so ashamed! I intended it as a slur that carries with it every horrible prejudice anyone harbors against you and your kind..."
Doug: "My kind?"
Max: "Yeah, but it's not a real word--just a random syllable I spat out."
