Only-Child-Syndrome
a teenager or young adult that still acts like a self-centered little bitchbaby because they were coddled by their parents for their entire lives. These motherfuckers will get mad if you forget their birthday, or miss even the smallest of parties or events. They will likely have close relationships with their neighbors to make up for the lack of siblings. They think that they are entitled to everything and are spoiled rotten by their parents and grandparents. You will likely find them complaining or more commonly whining. They are so sheltered, they likely have little knowledge on any adult-topics and an even greater lack of social skills. Do not get involved with an only child.

Get the only child syndrome mug.
A syndrom, mostly found in only children, where they talk to themselves, which is quite hularious to watch, they are perfectly normal, but they talk to themselves because being an only child, they had to intertain themselves because there ws no one else around to intertain them; in some rare cases this is found in people who are not an only child
