Wikipedia syndrome is a medical condition, believed to be caused by a virus, which gives you a sudden urge to write articles on the internet like you're fucking Bertrand Russell, and use really, really big words, before developing various diseases for no reason at all, such as leprosy, liver cancer, AIDS, halitosis, kidney failure, an affinity for cedar polish and pickles, and in most cases beaten up because nobody likes a smart ass. Oh, and don't forget lupus.
