The story
Coined by Jon Hendren in a 2007 post on Something Awful (see quotation below).
Today it means
noun The act of comparing two similar Wikipedia articles, one considered generally useful and the other primarily appealing to nerdy interests, and observing that (to one's disappointment) the latter is significantly longer and more professionally written.
