A rare disease in which, the affected may find themselves defecating Nexon game cards.
The cause of this is still unknown, but scientists believe that it may be caught by playing so much MapleStory, to the point that so much more NX cash is needed that the body adapts itself into creating plastic squares with valid NX codes.

In the beginning stages of this horrible disease, a player may find themselves holding a credit card in their parent's name and a chat box on MapleStory filled with pink messages they created for attention.

Often times, the player will not remember the incident.
In the second stage, the player will start buying equips for real life cash. Lots of expensive equips. Sometimes their aunts will shun them.
In the third and final stage of Nexiosus, the victim may notice intense pain coming from the rectum, where they will realize they are defecating a large blue or green square of plastic. This problem may or may not reoccur.
The treatment is simple, Stop playing MapleStory. But for some reason patients tend to play MORE when this disease is fully developed, it appears that they obtain a type of "High" or, sexual pleasure from continuing this process. You may ask yourself the question: "WTF?” But don't worry, WTF is a pretty damn good way to react.
Did you hear about that kid from Bellocan? The poor guy caught a nasty case of Nexiosus.
