Kibitz is a term that originated in Yiddish and is often associated with Jewish customs and culture. It is typically used to describe someone who offers unsolicited advice or commentary in a humorous or sarcastic manner. Some synonyms for kibitz include gab, chat, chatter, banter, gossip, prattle, and blather. These words all describe a form of idle talk or conversation that is often seen as intrusive or annoying. In some cases, kibitzing can be seen as a harmless way to pass the time, but in others, it can be seen as a form of interference or disruption of a serious or focused conversation.
