Canal Water 

Menstrual flow.

When Dionne Warwick was messed up on heroin in the early 1970s and a critic blasted her bizarre concert performance, she phoned the guy and screamed at him: "Yo mama suck canal water!"

Four-Sided Waterfall 

When someone gets drunk and throws up on a bar/restaurant table. In order to have successfully pulled off a four-sided waterfall, the person must have consumed such a large volume of alcohol that the liquid pours down all four sides of the table uninterrupted as if cascading from their mouth to the table, and finally down to the floor.

Friend 1: Hey guys! Check it out! Jon is throwing up on the table!
Friend 2: Dude, how much did he drink? It's totally spilling off the sides.
Friend 1: Looks like he made the Ole' Four-Sided Waterfall....

Night water

The water you drink when you wake up in the middle of the night that tastes like it came from a mountain spring blessed by God himself.

“Dude, that night water really hits different when you’re thirsty at 2am.”

Water Sheringham 

The most realistic name for a dolphin. Based on the fact that dolphins are complete and utter cunts who know something that we don't but are clever enough to let us know they know something without actually telling us.

In land terms the only thing as cunty as a dolphin is Teddy Sheringham, ex-Spurs footballer.

Dolphins are the Sheringhams of the water, therefore 'Water Sheringhams'.

Look at that Bottlenosed Water Sheringham herding that unfortunate swimmer out to sea where they will be eaten by sharks.

or

How can we sink that enemy submarine? I know, let's strap a bomb to a Water Sheringham and teach it to explode when they get close enough.

Beaver Waterfall 

A beaver waterfall is when a woman lies down in the bathtub, places both legs on the wall, places her vagina underneath the faucet, and uses running water to masterbate.

Sheila was feeling very lonely after watching "Murder, She Wrote" so she decided it was time for a beaver waterfall.
