Kool-Aid Waterfall 

When someone takes the top of the kool aid jammer off, and then pokes a hole in the bottom of the jammer and puts the bottle in the girls vagina. They then proceed to drink a mixture of kool-aid and pussy-juice out of the girls vagina.

She was amazing, she gave me the the greatest Kool-Aid Waterfall

Alaskan Waterfall 

In the climactic stages of oral shaft pleasures at the top of a well padded staircase, the male pulls the shaft out of said face hole and proceeds to swiftly jump kick partner down the staircase while ejaculating in mid air. This action should gain enough force to hit your partner as they fall thus completing the act.

As i swiftly kick my lover down the stairs, she cries out...nooooo not the Alaskan Waterfall again...

Buttcheek waterfall

When a person gets so hot that a tiny sweat resevoir forms at the small of their back. Once it reaches full capacity it begins to trickle or flow down the natural crevice tween one's ham hocks (buttocks)

"Dude! I was so sweaty from rollerblading! Springtime came early and I had a buttcheek waterfall ... Yosemite-style-Yo!"

Kansas Muddy Waterfall 

When a man is sitting on the toilet taking a steamy poo while the woman sits reverse cowgirl and bangs him hard while taking a piss.

Man, the other night when I was banging my girl Kansas Muddy Waterfall style while I was taking a massive shit, she pissed all over me!
