Flurfunk

Flurfunk: German has an extra word for “the informal gossip and office buzz that spreads quietly among coworkers, until everyone knows about it even though it’s not official, but turns out to be true in the end”

“To know something from the Flurflunk” is roughy the equivalent of the (equally great) English expression “to hear something through the grapevine.” It describes the “in-official” flow of communication inside a company or an organization.
