anything and everything, one of those words that you use when you cant think of the actual word. however, this word is special in that even if you cant remember the word your supposed to use, shitdik adequately expresses every emotion, idea, action, event, and everything else that ever was, is, and ever will be.
Guy 1: Hey, remember that one scene from Avatar?
Guy 2: yea, the one where they are sitting around the shitdik, talking about shitdik?
Guy 1: yea, its basically the same concept as a shitdik.
