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."
A wikidick is the token douchebag know-it-all posting all over whatever thread you may be viewing. This person loves to correct everything you say down to minute grammar.
Although commonly mistaken for a troll, or a grammar nazi, you'll be happy to know there is now a distinct difference.
A wikidick is someone who achieves superficial satisfaction by stalking threads and correcting any or all posters by way of leeching the popular site "wikipedia."

I was trying to have a conversation when some troll whore started spamming me. He keeps saying that my understanding of Greek architecture is limited and frankly insulting.

That's no troll whore. That's a wikidick who wants to be taken seriously
