Gullywasher

Chiefly Southern term for a heavy rainstorm.

They say the rain's movin' in, from the looks of it I'd say it's gonna be a real gullywasher

Gullywasher

A shit storm.

Billy done told us about that damn gullywasher coming boys. Y’all get ready for that damn rain fall.

You don’t know what a gullywasher is, you must not be country enough.
