When an over zealous fanboy hijacks and changes information in certain wikipedia articles to defame, libel, or completely destroy someone.

This can also apply to anyone that randomly goes on wikipedia, chooses a random, non-protected wikipedia article, and edits it completely without anyone's consent.

In other words, people that get joy from editing wiki articles to fit their own destructive/sick goals.

A combination of the words wikipedia and hi-jack.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.
