When you take out a person's glass eye and shoot your load in the empty socket creating a waterfall of cum from her nose and mouth
"Yo dude, we got drunk last night and picked up this gross bitch who had a glass eye. Ryan thought it would be funny to give her The Irish Waterfall, so he did. It was solid!!"
"Craig has an infatuation with The Irish Waterfall, I think his boyfriend likes it!!"

The Las Vegas waterfall is a sexual act in which a man urinates into a birthday hat. Then another person takes the urine and poors it down the man's back, while holding another birthday hat on his lower back in preperation to catch the remaining pee. As a result of this sexaul act, the man will climax. This act is called the "Las Vegas Waterfall" because prostitutes in Las Vegas have done this to an intoxicated man on his birthday.

When a girl is giving you head, and right before you cum you push your penis to the back of her throat, making her gag and vomit, while she is vomiting regurgitate all over her back and head making sure that your vomit runs into her's creating the double waterfall effect.
