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.

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.

Get the waterfall bong mug.
made by poking a hole in the cap of a bottle and the bottom of it. u then put a bowl in the hole in the cap and fill the bottle up with water (and put weed in the bowl). lite the weed and unplug the hole at teh bottle. at the water drains out the smoke should be pulled into the chamber. when all teh water has been drained out, take off the cap and suck in teh compressed smoke. if u wanna try sumthing cool, squeeze teh bottle as u inhale so it makes it into a gravity bong =)
man i hit that waterfall bong soooo hard.
