The word 'blackball' is usually used when a group of people is voting to decide whether someone should be allowed to join or participate in their group or club. If someone is 'blackballed', it means they have been voted against or rejected. For example, if a person wants to become a member of a sports club, but is disliked by a few of the existing members, they could be 'blackballed' and not allowed to join the club. It can also refer more generally to someone being excluded or not accepted by a group of people.
