Wiki troll 

A lifeless jerk that spends all day patrolling wikipedia articles and deleting anything that is not referenced regardless of its significance in order to make him feel like he is making a genuine contribution.
Also dominate article discussion pages, squelching any reasonable requests or questions brought up therin with unnecessary and brutal sarcasm.

My article on Cool McCool was deleted by a wiki troll as there are no references on the internet to source, yet he is obviously aware of the series' existance. Tosser.

Wikiroll 

A trance-like state where the user moves uncontrollably from link to link to link to link on Wikipedia, absorbing new pages. The roll often ends suddenly, halfway down a page about Japanese funeral rituals. The user will emerge dazed, confused, but considerably more informed.

"Dude, where you been? Your eyes are all bloodshot and your finger looks swollen. Were you on Wikipedia again?"

"I didn't mean to wikiroll! I just wanted to know if Barack Obama was from Kenya, and I woke up reading about stained glass techniques in Renaissance churches. Why does this always happen to me?"
