Jungle telegraph is a term that refers to a network used to spread information, typically used in remote or undeveloped areas. There are many synonyms for the phrase, such as bush telegraph, grapevine, coconut wireless, and rumor mill. These terms all emphasize the idea of information being passed on through informal channels and often without direct communication between individuals. Other synonyms include word of mouth, hearsay, and whisper campaign. All of these terms have a negative connotation, suggesting that the information being spread may not be reliable or accurate.
