At the start of your gathering, introduce the jellyfish ground rule: If any attendee feels the conversation is heading off course or delving into an inappropriate level of detail, they can and should employ the word to indicate that opinion. Simply say “jellyfish” or “I think we’re having a jellyfish moment” or “Gee, did I just see a jellyfish swim by?” It’s a catchall for “Why don’t you take this offline—the rest of us would like our meeting back.”
