What does the phrase "the black ball" represent in Masonic tradition?

In Masonic tradition, "the black ball" is a significant term that specifically refers to the method of voting on a candidate's admission into the fraternity. When a candidate is proposed for membership, existing members cast their votes in a ballot, which often includes white balls for approval and black balls for disapproval. The presence of even a single black ball can result in the rejection of the candidate. This practice emphasizes the responsibility of current members to ensure that candidates are suitable and meet the standards of the Lodge. The black ball thus plays a critical role in maintaining the integrity and values of the Masonic organization by allowing members a vote on who is deemed worthy of membership.
