A colorful piece of American dialectal slang for an exceptionally heavy downpour of rain — the kind that comes down in sheets and floods roads in minutes. 'Cob-floater' is vivid rural hyperbole: a rain so fierce it could float a corncob right off the field. You might hear it from older speakers in the Midwest or South when describing a proper gullywasher of a storm.

We had to pull over on the highway because that cob-floater came out of nowhere and we couldn't see two feet in front of us.
Origin: American dialectal expression; 'cob' refers to a corn cob, and the image is of rainfall so heavy it would float even something as large and buoyant as a corn cob. Editorial expansion authored on Slangora (model-assisted, hedged).
