plot-hole

(n): like an open pot-hole, but within a plot. since i work in publishing, this is like my new favorite word.

example: "the manuscript was OK, except for the giant plot-hole in chapter 4."

theorette

(n): something that is proposed as a valid theory, but is really just a piece of bullshit.

as seen in a comment to this article on the new freakonomics book (and why it sucks).
