noun. An adventure through wikipedia, usually started by looking something specific up, but eventually taking hours and only ending when the articles get too boring or you force yourself to stop. Related to a wikiwander, but usually with more zeal or interest.
My boss gave me the day off and I was looking something up, but it turned into a wikiventure. I ended up wasting the whole day, but it was worth it!
