Wikipedic

From the National Puzzlers' League mailing list, comes my favorite recent neologism:

At a party I was at recently, a new term was introduced: "Wikipedic", by obvious analogy with "encyclopedic". Intended usage: "I have a Wikipedic knowledge of X". This signifies that you know a great deal about X, in the form of facts you heard or read somewhere you don't really remember and whose accuracy you can't vouch for. But it's probably mostly right.
