The complete and hasty disappearance of nearly all of the normally external, and usually erect, penis which can result from one of many atrocious turnoffs which a female sexual partner is capable of during or immediately prior to intercourse.

Disney Syndrome takes its name from, you guessed it, Disney. It covers the range of beliefs children have been taught from Disney movies. These children grow up believing these movies to be right and are often disillusioned in adulthood even when shown evidence that life isn't a Disney cartoon.
For example, the idea that little girls will find the knight in shining armour to sweep them off their feet (ie, that perfection in a partner exists), or the belief that wild animals are all cuddly and nice (ie, that bears won't maul you for petting their cub), or that someone will take care of things for them when they are at their lowest are all symptoms of Disney Syndrome
