Tracing its origins to high school kids in Las Vegas, Nevada, the act of drinking from a friend's soda or water without your lips actually touching the bottle. Share your drink, not your germs.

Throwing something in the garbage, or at least out sight, in such a way that is no longer visible nor your concern for the foreseeable future. Originally used by early Intel engineers who would literally throw obsolete or malfunctioning equipment off a waterfall near their laboratory.
Engineer 1: This CPU doesn't work!
Engineer 2: That's the old version. Waterfall that piece of crap.
Engineer 1: Off the cliff into the water it goes!
Engineer 2: Where won't have to ever see it again!

While a girl is sitting on a toilet urinating, another person comes up and urinates on her stomach and or chest. The multiple streams falling into a common pool make a refreshing sound similar to that of a waterfall.
To save time while at a party, I ran into the bathroom while a girl was peeing and tried my best to spray in between her legs. Sadly I frequently missed and ultimately waterfalled her.

When you are having sex and just before jizzing whip it out of the hairy dog and cum in a straight horizontal line accross the area between the mouth and nose, she opens her mouth wide and sticks her tongue out. As the jizz slowly slides down into her mouth and then she swallows.
Kanye: Do you know what I did last night with Kim;) ?
Micheal: what!
Kanye: I surprised her with a waterfall! And she was there for ten minutes before the flow finally finished!
