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"

Cascading Waterfall

To aim one's penis just right so at the point of ejaculation the stream of sperm flies overhead, narrowly missing the face in a matrix like fashion. Resembling a waterfall.

"Last night I was masterbating and totally shot a cascading waterfall"

Gouch Waterfall

When one's balls are sweaty enough to create a trickle flowing down the gouch and dripping right before reaching the butthole.

Damn homes...it's so muggy out here my gouch waterfall could fill up a pint glass.

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