a sufferer of a rare syndrome that affects 1 in 6.7 billion children. It may cause the sufferer to break out spontaneously into disco-dancing for small change on the streets, say and do utterly retarded things and embarrass any elder siblings to the point of disowning the sufferer.

A mysterious individual who reveals little about himself. Some may think they know him well, but the fact is, they probably don't. Some people call him funny. Some, witty. Some think he's an idiot. Whilst others say he is extremely intelligent and socially savvy. No one really knows who he is. But some say he is dangerous. He comes into people's life just as quickly as he leaves.
Where is Nish?
