BLACK BALL

In most traditional secret societies in the western world, candidates for initiation are elected to membership by a secret ballot of current members of the lodge where their application has been received. The usual method involves a wooden ballot box with a tray of white and black marbles. One at a time, members advance to the box, pick up a marble and drop it in. White marbles are favorable votes, black marbles unfavorable. In the stricter lodges, one negative vote is enough to bar a candidate from membership, while some American fraternal orders now require a majority of negative votes to exclude a potential member. See fraternal orders; lodge.

The custom of voting in members with black and white balls was widespread enough that it gave rise to the verb “to blackball,” meaning to ostracize someone or block their membership in an organization.
