In Dutch we have a saying that "the tamtam does its rounds" when a rumour has been passed on and a lot of people have heard the news. This can either be in a negative as well as positive contest [tamtam refers to the hitting of a drum, like in ancient tribes].
Is there an English equivalent to this saying?
Just remembered another: 'the jungle telegraph'.
'I heard it on the bush telegraph.'
(This use of 'bush' - meaning, roughly, 'not very dense jungle' - is associated with parts of Australia and parts of Africa; I'm not sure about other continents. In the UK, people don't talk about local landscape as 'the bush' - except in a jocular way. Example: 'If I don't do something about the garden at the weekend, we'll be fighting our way through the bush with machetes!')
