A vivid American dialectal expression from the South for a torrential downpour — rain so heavy it could float lightwood knots (the dense, resin-soaked heart of pine trees, famously heavy and difficult to move) off the ground. The phrase captures the hyperbolic Southern tradition of describing extreme weather.

It came down a regular lightwood-knot floater that afternoon, and the creek was over its banks by nightfall.
Origin: From Southern US dialect: 'lightwood knot' (the dense resinous heartwood of longleaf pine, extremely heavy) + 'floater' — rain so hard it floats even these famously heavy objects. Editorial expansion authored on Slangora.
