The waterfall 2.0 is a spin-off version of the sex position: ‘the waterfall’.

What’s different is that the position is in a running shower instead of from a bed or couch. In a running shower it’s alot more like a real waterfall so that’s what makes this positon so much better.

Due to the fact there’s no bed in the shower the man would have to adjust his position slightly.
Jack: (To his girlfriend) we should try that new sex positionthe waterfall 2.0’ later

Jill: What’s that?
Jack: It’s like ‘the waterfall’ but in the shower

"You're singing it wrong bb! Those aren't the lyrics!"

"Idc.. Not just about this, Idc about anything..."

1. (n) The most effective device for smoking marijuana known to humans. The standard waterfall consists of a Gatorade bottle with a circular hole burnt at the cusp of its base, and a tin foil bowl built into the bottle's belonging cap, constructed to hold 0.1-0.2g of marijuana (1 "wat"). It is used by first holding the carb and then proceeding to fill the bottle with water. Once filled, the cap (filled) is to be twisted on and the smoker, after first igniting his lighter immediately above the bowl, is to release the carb and drain the entirety of the bottle into a designated water-collecting source. Following drainage, the smoker is to promptly re-cover the carb and proceed to untwist the cap. Immediately upon cap removal he is to cover the whole with his mouth, release the carb, and inhale the whole of the chamber. The breath is to be held long enough for the exhale to be barely to not visible. If used properly, it is the only known device that yields 100% of smoke for the user's consumption. Furthermore, it is the instrument with the optimum output high as it is simultaneously the instrument that requires the least input nug.

Standard consumption:
Wat - 1 wat
Half - 2 wats
3 Quarters - 3 wats
Full Game - 4 wats (you'll be on your bum-bum)

Now you know the method of the gods.
1. (n) - "And God said, 'Show them the way of the waterfall bong.' And I trembled and said to him, 'Lord, y-you mean to trust me with the sword of the heavens?'

2. (v) - My college philosophy professor asked me to prove to her that less really was more, so I ripped a wat in her stupid pregnant face.

Satan's waterfall is another word for having your period. This is referred to satans waterfall because satan means evil and hell (basically what a period is) (oh and because satan normally associates with the colour red like a period) and waterfall means the constant flow of blood.

the washington waterfall is the erotic act involving three highly inspired individuals. two of the companions consume copius amounts of exlax and await the flood from ass. all participants strip naked. the two that consumed the exlax position themselves bent at 90 degree angles with their assholes kissing. the third party lays face up below the two, the two simultaneously realease the liquid terd stream. the two streams join forces and catapult downwards into the waiting open mouth of the thirsty (and may i say lucky) third party.
steve was having trouble getting off lately, so we had a party and performed the archaic act of the washington waterfall so he could reach climax.
