rock waterfall

Urinating on one's own scrotum, often by accident.

Steve's pants were too tight, and it was very hot out. He had to keep drinking water, so inevitably he wound up having to pee. He entered a McDonald's, and when he got into the bathroom, he realized he also needed to poop. So he sat down on the toilet, and as he let out his stream of urine, he did not yet realize the degree to which sweat had glued his scrotum to his shaft, and received a rock waterfall.

I need to wash up, because my girl just gave me a Kentucky waterfall and I smell like urine.

Redneck Waterfall

A mullet. The "business up front, party in the rear" looks like a waterfall cascading down the poor hillbilly's neck and shoulders

1: Dude, did you see the mullet on that guy?
2: Yeah, that thing was a redneck waterfall.
