Discrimination against a member of a House (Hufflepuff, Ravenclaw, Gryffindor, Slytherin), usually hateful language used by a member of a different house. Often is used to show supposed superiority between houses.
By calling his friend a dumb Hufflepuff, Harry was showing a level of Housism not tolerable at Hogwarts.
