Top Definition
A term literally meaning inflammation of the douche. Clinical psychologists are currently using this term to describe a sexual disorder that causes individuals to transfer their sexual desires into the sexual behaviors and fetish of World Domination. (see World Domination) The disorder is commonly found in individuals working in middle to upper management for large corporations, investment bankers, business entrepreneurs, politicians and women who are nursing or pregnant.
The exact cause of the disorder remains yet unknown to psychologists. However, psychologists have observed many similarites in males and females who suffer from the disorder. Males with douchebagitus are often found to have ridiculously small sexual organs. Both the penis and testes are considered by clinical psychologists to be "hilariously small". In extreme cases some males often only have a urethra without a shaft. Females with the disorder often suffer from little to no nerve activity in their sexual organs.

Psychologists theorize that the lack of regular sexual satisfaction in these individuals causes them to slowly become bitter towards the world until all their desires are manifested in World Domination, wherein they receive sexual satisfaction.

A contagious form of douchebaggery where a person you hang around with is such a douchebag, it rubs off on others where they too become douchebags.
I must have douchebagitus because my friends were decent when I met them. Now they are all douchesniffers.
