Takingtoytowntooseriouslyitis is a queer illness that affects exclusively members of the Toytown Germany chat forum, mostly those who are in the disillusionment phase of their membership cycle. There is no known cure. A prolonged case of Takingtoytowntooseriouslyitis can, and often does, lead to the afflicted user deciding to flounce.
Similarly, there is also Beingoverlyhighlystrungitis. This is not a TT-specific malady, but nevertheless many TT'ers do seem to exhibit it.
Candishitoutbutnottakeititis is also common on TT.
An unusual condition that one TT'er seems to exhibit is Whodoeshethinkheiskiddingitis. Symptoms include posting details about his personal life and thinking that by saying it was a "friend" or "work colleague" anyone is going to be deceived. See: I'm asking for a friend.
