the vagina waterfall 

An act of oral sex that requires the woman to lay on her stomach and prop her booty up. Upon doing so, several drops of water must be poured onto her booty. As the water trickles down the middle and down to her vagina, it must then promptly be licked up.

Hey man, last night my girl went crazy when I did the vagina waterfall with her.

The Irish Waterfall

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!!"

Irish Waterfall (Irish fish market, Luck of the Irish, Drunken Irishman) 

It's when a guy takes a full beer (preferably Guinness) and empties it in a womans vagina during intercourse. The man then proceeds to drink the alcohol from the opening as it flows out in similarity to a waterfall.

An Irishman is having sex with a lady, and decides to pour his beer right down her vagina in order for him to go drink, and lick it out while pleasuring his companion. This is then called an Irish Waterfall (Irish fish market, Luck of the Irish, Drunken Irishman).
