When someone edits their own wikipedia page. If a wikipedia page includes so many details that only a majorstalker would have written it, or it whitewashes negative aspects of a person's life, it was probably wikibated.
"Surely no one's that big a fan to know that much about SteveSax. He's obviously been wikibating."
Wikiwalking is a speed game which two or more people can play on Wikipedia. They choose a start page and an ending page. The first one to the final page wins that round, and normally you play the best two out of three.
