a young boy that hits puberty early and has features of a man. Also known as Man-Child Syndrome, this disease affects a few children every day and causes them to feel out of place in the world because of their ridiculous strength, looks and the ability to get older women.

A terrible disease that typically effects only-children, but can occasionally strike people with siblings. It may also effect children whose parents divorce.
Symptoms include: playing mind games with members of the opposite sex, a cripling desire for instant gratification, the inability to compromise or share, and a total disregard for anyones thoughts or feelings but their own.

Only children sometimes exhibit characteristics resembling women who have their periods. This can occasionally lead to flashes of intense anger when they don't get their way or someone insults them even the slightest bit. Also, when there is dissent in the friendship ranks which they are a part of, they lash out and try to make the other friends seem more culpable and especially more gay than they are. They have an overwhelming feeling that the world is against them and they tend to ruminate a lot as well. When you factor girls into the picture with an only child, it is never a pretty sight.

Lack of Motherly Hug Syndrome (LMHS) is a very rare condition that a child endures when not receiving enough hugs from their mother, or a very meager, to no amount of affection. It is very uncommon to hear of LMHS, but it exists in families in which the mother is very mean and does not like to hug her children.

2)someone who does not seem to age (aka Patrick Swayze syndrome)

A form of mental illness. Symptoms include the tendancy to throw a massive tantrum about the smallest of things, a need to have everything his/her way, and an inability to form friendships with other human beings.
