A game in which you are at an article on Wikipedia. And you have a goal article. Which is a completely random article that you have to get to by just using the links on the pages. Only played by the l33t.
Dude I so fucking PWN3D at a Wiki Drift tournament last night
Similar to google drift, but using the search on Wikipedia. It is actually far easier to get much farther off topic when wikidrifting, becuase of the links attached to every word in a Wikipedia entry that has it's own entry.
One day I was trying to find out how to correctly spell "the Fonz" so I looked him up and somehow wikidrifted to the entry for "portmanteau."
