only child 

Someone who has no siblings. Some upsides are getting what you want, having some friends that are only children, no being irked, and having higher goals. Downsides are lashing anger on kids who have siblings, and can end up being a jerk. Sometimes it leads to having an inflated ego.

Friend 1: How's your sister?
Friend 2: Pretty good. She's playing soccer.
Only child: I'm frickin' tired about my brother that, and my sister this! Screw all of you! *walks away*
Friend 1: God, what a jerk.
Friend 2: I know.

only child 

the Only Child is a clever species which mimics the Regular Human. Indistinguishable by simply looking at them, you must get to know an Only Child to know that they are, in fact, an Only Child. As a species they tend to appreciate being alone more so than the Regular Human, and more often like quiet thinking time and don't mind hanging out by themselves. At a young age, all Only Children tend to go through an elongated "brattiness" phase, which tends to be more extreme than that of a Regular Human child. Depending on the parents, the Only Child may eventually grow out of this phase, and surrounded by Regular Human friends, can blend in perfectly. The Only Child has been observed to experience loneliness quite often, and usually feels that this loneliness can be filled best by a relationship, and extreme cases the longing for a relationship can be more important than maintaining the type of friendship observed in the species "Regular Human". However, it is indeed common for an Only Child to fall harder and faster when it comes to relationships, and tend to experience emotions more intensely. If an Only Child has trouble finding an acceptable relationship, they may become uncomfortably hormonal. For example, it is possible that a female only child could even have as many hormones as a 17-year-old male. Which is a fuckton load. Only Children also love Pokemon, especially Wooper.

1. Bro 1: If I ever have kids, I'm def gonna have more than one. I don't want to have to raise a bratty, over-hormonal only child.

2. She must have gotten through her annoying only child phase, because we've been friends for years and I just assumed she had siblings.

3. Duder 1: Man, that bitch is such an only child. When I asked her to fuck she got all emotional and now she's telling people we're dating. WTAF.

Only child 

Only children vary. They don't know what it is like to have a sibling and to have that bond. They also are not at all independent as they rely on their parents a lot more than a usual child. Only children are often more shy and reserved but are always very close to their parents. They are often very spoilt and know very little about life. They can sometimes find it hard to make friends as they sometimes lack in personality. They do, have a much nicer relationship with family, and are often kinder than usual children. They can have anger issues and tantrums sometimes though. They are less tough than some kids as they haven't been through the trauma normal kids have. They also don't have siblings to keep them in line so they often step over boundaries. If you are friends with an only child you must make sure they stay in line and make sure you are like the sibling they never had. They don't know what it's like to have siblings but are still jealous of those with siblings. They need someone like a sibling although their parents often try to be more like their bestie than their parent.

I would hate to be an only child.

only child timeframe 

A term that describes the distortion that occurs when someone who’s an only child who grew up regularly distorting or misperceiving time intervals ballparks how long something is going to take.

When she gives me one of her only child timeframe estimates, I just double it so I don’t lose my mind.

Only Child Syndrome

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.

Example 1: Man, that girl is such a bitch- she wouldn't even spare a square! She has the worst case of only child syndrome I've ever seen!

Example 2: My boss has the worst case of only child syndrome ever! Every time I do something good he finds a way to slam me down just so he can feel better about himself.
