Rocky Waterfall

To have a 'Rocky Waterfall' is to simultaneously urinate while having a dump.
Example 1. "I was so desperate for a wee, that when I was shitting I pissed at the same time. It looked like a rocky waterfall."

Example 2. "I was desperate for some really kinky porn, so I looked up golden showers with scat. What I got can only be described as a rocky waterfall"

That gouch waterfall I dealt with all day made these boxers smell rank as fuck.
