Stereotypical analysis of men of shorter stature. Based on the fact that some shorter men act more aggressive to compensate for lack of height. Yet failing to realize not every short guy is like that. Some men are just aggressive whereas others need to be more assertive. (Peep this: No two people are exactly alike)
Ex.1
Guy:That one short guy in the group tried fighting the bouncer. No reason at all. He's got short man syndrome.

Guy2: Yeah I saw that, but that other short guy was just chill in', talking and dancing with women. He's got more confidence, doesn't seem to care about his height.

This typically describes a man under 5 foot 5 inches. Short man syndrome men usually have a heavier body, a small head , but a larger face, typically are going bald. A man with short man syndrome will try to overcomensate for his small stature by buying oversize cars, always lying, being very controlling, very bossy, and think they are always right. They cannot admit they are wrong. They will align themselves with the people they think can do the most for them, and will use people to their advantage, lying about everything. They will cruise myspace, facebook,...ect... for hours trying to find friends that are female (that they dont really know) just to give the impression that they are popular with the ladies.
Mike bought a oversize SUV even though he could not afford the gas, cause he wants the girls to focus on the car not that he is short. He has short man syndrome.
Nick invite every girl onto his myspace to look like he is popular.

A term used to dehumanize short men. On the basis of this prejudiced term, a short man isn't allowed to do anything assertive, confident, or generally masculine without being accused of overcompensating or having short man's syndrome.

Whereas if a taller man exhibited the same exact behavior, nobody would bat an eyelash.
I rudely shoved that short guy at the bar out of my way, and he got all angry about it. Talk about short man's syndrome!

Also known as Napoleon complex

A very annoying and obnoxious syndrome. Short men come down with this when they realize they will always be the smallest adult in the family, group of friends or place of business.

They can also become violent against the wife and children, like a scene out of the movie The Shining.
