Sheep

1) A person who exclusivly follows a group, movement, political party, organization, etc., and tends to hold the opinion or ideals of this group in high esteem, even if the opinion/ideal is negative or is problematic. This is generally because of a positive bias towards this group, or a negative bias towards groups who represent the opposite viewpoint. Often, people who fit this definition of "sheep" are assosiated with negativity, and are accused of being uable to "think for themselves." 2) Similar to deffinition 1, a "sheep" can also refer to someone who is a fan of certain types of entertainment (ex. music, film, etc), simply because it is popular, and it therefore reflects positivly on this person if they are a fan. 3) A common farm animal.
