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
