when a girl is passed out at a party you drag her into the laundry room, then you pull down your pants stand over her face then pour cold water on her face then she will sit up quickly, right into your ballsack. her ice cold face will give the sensation of a waterfall.
Waterfalls are so refreshing

When you hear a guy pissing in a toilet while he's standing up (Which makes a "waterfall" sound). When you DO hear a waterfall, scream "WATERFALL!!!"

to drink from somebody else's soda or pop by holding the can high, over your mouth and slanting it so that the drink falls right into your mouth without having you touch the can with your mouth; which would be unhygenic

To blend any two liquids (Mentos if desired) together and pour the mixture down your girlfriend's vagina and/or on her face. The mixture can be any two liquids, so fuck around with the Diet Coke.

When someone asks for a drink of something you already put your lips on, the pour it in to their mouth, which looks like a waterfall.

When a woman squats over the mans face before squirting and lets her holy refreshing water run into his mouth. Have you tasted the spring of life yet?
