When a man comes while a woman is sucking his dick and it seeps out of her mouth down on his cock.
I felt kind of nasty last night so I let my woman give me a waterfall. Had to take a shower after but it was worth it.
What most certainly happened to Cleavon Little at one point during the night with Madeline Kahn in Blazing Saddles.

While a girl is sitting on a toilet urinating, another person comes up and urinates on her stomach and or chest. The multiple streams falling into a common pool make a refreshing sound similar to that of a waterfall.
To save time while at a party, I ran into the bathroom while a girl was peeing and tried my best to spray in between her legs. Sadly I frequently missed and ultimately waterfalled her.

When you are having sex and just before jizzing whip it out of the hairy dog and cum in a straight horizontal line accross the area between the mouth and nose, she opens her mouth wide and sticks her tongue out. As the jizz slowly slides down into her mouth and then she swallows.

An improvised smoking device mainly used for smoking hash resin through. This is traditionaly made from a 2-5tr plastic bottle with a 5mm hole melted into the side about 10cm from the base. With one finger covering the hole the bottle is filled with water. A head (13mm socket set + gause with a thin band of "Sticky Tack" wrapped around the outside to produce an airtight fit) is then filled with smoking material and placed into the top of the bottle. Then the user removed their finger from the hole letting the water flow out from the side of the bottle while holding a naked flame (lighter/match) above the head. The drop in air pressure inside the bottle caused by the water draining out pulls the flame into the head which in turn ignites the smoking material filling the inside of the bottle with thick 'cream cheese' type smoke which (after removing the head from the neck of the bottle) the user then sucks/inhales the smoke in one deep breath (unless they are a lightweight) XD.
Most smoking noobs fail to grasp how a waterfall should be used correctly so their knowledge on the subject ends here.
Because the hole is made in the side of the bottle not the bottom there is a certain amount of water that remains in the bottle this is not a design flaw. The idea is then to remove the head then place a finger over the hole in the side of the bottle and a thumb of the other hand over the top of the bottle. Then violently shake the bottle for a second or two. Because THC is not soluable in water only the impurities in the smoke will get absorbed into the water (nicoteen etc). Not only is the smoke cleaner but it is also much cooler so the user is less likley to have a coughing fit when trying to inhale the THC vapour.With a lot of the impurities removed the user recieves a much higher absorbtion of THC into their bloodstream than if they were to use the same amount in a normal pipe.
"hey i got some hash.."
"cool lets make a bong dude"
"..Nice idea but i havent got anything to use as a down pipe"
"fuck it what about a bucket?"
"..nah they just choke me out.Its to much for me"
"hmmm....hey what about a waterfall?"
"woo hoo!... now your talking"
