Wikihawk

A person who has claimed responsibility for an entry on a community sourced website (like Wikipedia) and who refuses to let others update the entry in question.

Oh no! I updated 'Snickers' on Wikipedia and a wikihawk took it down less than a minute later. My professor is never going to give me credit for the update now.

Wiki Hawk 

Frequently referencing Wikipedia while watching a t.v. show to find out interesting historical facts about the program's cast.

Surfing Wikipedia continually out of sheer boredom.

Ex. Tonight, while watching Family Guy, I was being a Wiki Hawk and found out that Seth Mcfarland used to be a writer for the cartoon Johnny Bravo.
