Wikigroaning (whih-kee-grow-ning): A game where players attempt to find two vaguely related Wikipedia pages, the first being something real people might actually wish to research, and the second being an entry that absolutely nobody really needs to know. A Wikigroan is of extreme quality when the second entry is much longer and more detailed than the first: e.g., Sgt. York versus G.I Joe.
Some of mine:
Okay, those are mine. Let’s see what you people come up with.
(Hat tip to Leonard Pierce for the example Wikigroan.)
