Stereotype

Something that is not entirely fact, but is also not based entirely on fiction either. Not every single black person can jump, but many of them can, enough of them can. Not every single Asian knows martial arts, but many of the martial arts started in Asia (not all). Not every Italian has been in the mob, or knows how to cook, but the Italians had a mob, and enough Italians are good cooks. Not every single Irish guy has a short dick, but many do, enough of them do (that includes me), or a bad temper, or a drinking problem, but even if the lace curtain irish feel embarrassed and dont want to be associated with the stereotypes, they got started for a reason, even if they're not a fact for everybody in a population.
