No, not that I am aware of. I created that word last year or early this year as part of a writing contest for Hard Fork, a new series that is being filmed. I googled that word and nothing came up in google, bing, or yahoo. Websters didn't have anything either in the dictionary. 
So I ran with it giving it my own definition.
Now since I have been using it there are several of my daily dose columns that show up on a google search for the word "guzbuck" . I know that google has different results for different parts of the world so I don't know where you are or what those might be.

 I do know that a follower of the Daily Dose from Berlin Germany googled it where he is and said that he found it listed in his results. In fact he said, "It looks like you must have created this word" since the only results it showed were daily dose columns. 
It might be considered a "no fly zone" soon, just like the F-Bomb is in some places, that word doesn't fly well in schools and courts and such.
 So in answer to your question, no... not that I am aware of.
