Waterfall It
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.
Tyler: Yo dude can i have some of your gatorade?
Dan: Sure as long as you Waterfall it.

Waterfall
to drink from somebody else'ssoda 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
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.
This is when a group of people begin drinking their alcoholic beverage of choice, and the 2nd person in line doesn't stop drinking until the first person stops and the 3rd doesn't stop until the 2nd stops etc.
*such as when playing Kings* Oh shit you pulled an ace, time for a waterfall.
