hear a pin drop, one/you could(redirected from one/you could hear a pin drop)
hear a pin drop, one/you could
Complete silence. This hyperbole dates from the early nineteenth century. An early appearance in print is in Susan Ferrier’s The Inheritance (1824): “You might have heard a pin drop in the house while that was going on.” Although pins are a far less common household item than they once were, the expression survives.
