Wankerpediac
A Wankerpediac is a person on Wikipedia, who despite not knowing their own definitions, enjoys deleting every artcile they come across. Not unlike the Pyromaniac, they more than likely sit back and masterbate after watching their glorious work take place. Which is probably a healthy action since they are such sexually repressed geeks.
those Wankerpediacs erased my article on Anna Nicole Simpson's breasts again. Damn geeks!
