Condition which causes a person to use his position of authority to threaten or speak to others in a condescending tone. It is most common in police officers, military, security guards, rent-a-cops, teachers, parents, etc. When not 'on duty', those with LDS are quickly revealed as cowards.

The anxiety of knowing one's penis is extremely small. It's sometimes also refer to as Micro Penis. Most men who have Little Dick Syndrome are unable to satisfy women sexually; Young girls who have never had a sexual relationship would remain pure after having intercourse with such a man. Due to the size of the penis or lack of; he would be unable to break the young girls hymen during intercourse, therefore leaving her a virgin after their sexual encounter.

These men are angry. They are angry with themselves (expressed as self hatred and depression), and with women. They are angry, in some cases, at the world. These men are distrustful. They do not trust that any woman would ever tell them the truth.

In some cases, the penis is actually inverted...meaning that one's penis is so small that it hides up inside the body. This occurs in some extremely overweight males, giving them the feeling of not being worthy. Some of these men take their Little Dick Syndrome out on women, becoming abusive both physically and verbally. They like to find unknowing women via the internet, just for a slim chance that some women would actually want something to do with them. After one time of 'love making' these women usually flee, never to be heard from again.

Ninety-nine percent of these unfortunates are unable to slide their dick far enough into a woman, therefore, reproducing is almost impossible.
