Acid Waterfall 

Diarrhea that burns. Usually occurring after a hard night of drinking or food poisoning, being sick, etc.

Don't go in the bathroom, I just had an extremely uncomfortable acid waterfall in there. It smells horrible.

Scio Waterfall 

While you stand and a chick gets on her knees and starts blowing you, you throw up on her. So named for the shitty Oregon town where this first originated.

"Hey, dude, did you finally get Jen to play magician last night?"
"Yeah, but I fucked it up and pulled a Scio Waterfall on her. Apparently she's still trying to wash chunks of the chicken mcnuggets I ate out of her hair."

Rusty Waterfall 

The act of standing astraddle over another person who is laying on the floor while you pour a beer or other clear beverage down your ass crack, thus allowing it to cascade rustily down into the other person's open mouth.

"Don't kiss that girl! She got a Rusty Waterfall last night!"

Satan's Waterfall 

Satan's waterfall is another word for having your period. This is referred to satans waterfall because satan means evil and hell (basically what a period is) (oh and because satan normally associates with the colour red like a period) and waterfall means the constant flow of blood.

"ik our periods hurt like hell" says emily's friend
