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!!"

Get the The Irish Waterfall mug.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).
