An individual who is so stupid, ignorant and inept that their breathing and existence in any environment or location should be considered a crime due to their inhalation of oxygen that would be better utilized by others.

One who leeches off other people, scrounges off their parents, annoys everyone they come into contact with, refuses to work, stays in bed until mid afternoon most days and wastes what money they do have on gambling machines and often has a lazy eye. Otherwise known as a parasite
