Most commonly affects teenage guys. Only Child Syndrome is a terrifying disease to those who approach the infected. It most commonly infects only children, but in some rare cases people with siblings have been known to have the disease. Symptoms are selfishness, inability to comprehend other people’s feelings, and overall brat-like behaviour. If rejected in any way, for example, a breakup, those who are affected by Only Child Syndrome will most likely isolate themselves in an attempt for attention. Do not, under any condition, pander to these pathetic cries for attention. It’s all for a bit of drama.
Person 1: Mate, Alex told me that I would let him have my phone if I truly loved him!! How lame is that?

Person 2: Ignore him, it’s Only Child Syndrome.

This is a sad disease that only affects only children with the rare case of divorce kids and siblings with a big age gap. This disease spreads in multiple different forms. Symptoms include being bratty, self centered, clingy, always searching for gratification, or being a total asshole. A poor child with this disease will only be effected by a few of these symptoms, never all of them.
Why is Jessica always so clingy? Yesterday I had to drag her while she clung onto my foot. She has major Only Child Syndrome.
