The term "Black-balling" somebody, or "Being Black-balled", comes from an old Freemasonry practice when electing new members.

Current members would elect a new member by throwing either a white or a black ball in a box, and the new guy become a member based on the difference between white and black balls in the box. In some Lodges a single black ball would be enough to disqualify a hopeful candidate for membership, hence the term "He got Black-Balled".

Told you - history is cool!
