Wikidiving 

The act of aimlessly clicking through links in an online wiki, such as Wikipedia, often driven by boredom and wanton curiosity. This is facilitated by the fact that most wiki's are crosslinked everywhere, so you may very well look up "Potato" and eventually wind up in "Vaginal Suppository".

I got sucked into a three hour wikidive last night, starting at "Animal farm" and winding up at "Crush Fetish."

"I'm sorry I missed your call yesterday. I spent 3 hours wiki-diving and neglected to answer my phone."
