An abnormal, chronic condition that utterly destroys the spirit of those unfortunate enough to be affected. Victims usually enter an initial phase of existential shock coupled with long bouts of heavy, heavy introspection. Symptoms usually include a decreased will to participate in all social activities, as well as a general lethargic and depressing outlook. This disease is highly infectious and may be transferred merely by word of mouth in fortuitous circumstances. This disease carries no race bias.

Treatment: Direct intervention by loved ones, making significant amounts of money, getting laid.

It is a condition where a small or short man will be generally more agressive towards tall or larger men.

The person with Little Man's Disease is trying to make himself seem stronger or better than the bigger person and is generally hostile or moody towards them.

Little Man’s Disease: A disease of short males marked by aggressive antisocial behavior and constant overcompensation resulting in pompous mannerisms such as spitting, twitching, swearing, speaking loudly and tough talk.
The disease only affects teenagers or men who are less than 5’ 6” tall. The severity of this disease is inversely proportional to the height of the sufferer. Other characteristics of this scourge are a very short penis, acne, low I.Q and bad etiquette. The poor bastards usually drive jacked up pick-up trucks lacking mufflers. Often these males are homophobic to the point of insanity because of latent sexual orientation issues.
You must have Little Man’s Disease.

Is the condition - which generally affects older malse, post mid life crisis. Symptoms include clearly overcompensating for lack of plausible "mojo". Being an absolute douche bag yet being blissfully unaware.

Old man short dick disease can generally be identified by his balding head, prestigious car such as a Lamborghini, Ferrari or Maserati and is at most times accompanied by a perky blonde in her 20s.

Yet don't be fooled this is the full extent of this mans alluring qualities.
When you drive past that Lamborghini and see an 58 year old man, generally unatractive and balding. Promo girl in the passanger seat with a great boob Job - you can now think to yourself
