The best home made smoking device ever. A small spaghetti jar with a hole drilled in bottom and side, and the cap has a nut JB welded on top with holes beneath it. Use as a waterfall bong with the help of a friend. Perfect hits, everytime.

Not to be confused with Beast, beast, beastly, beasts or The Beast of Revelations. BEAST is an individual person with enourmous size and (presumed) enourmous strength. The strength is of course always assumed, because BEAST will never demonstrate this enourmous strength to those around him. While beast can refer to someone attractive, unnatractive, strong, or otherwise positively or negatively noteworthy and Beast can refer to individuals possessing qualities of the sort, BEAST must refer to the specific individual who embodies these qualities. While each social group has only one, and each group believes that it's own BEAST is superior, stronger, or more beastly than other BEASTs, it is logical to assume that there are many BEASTs in the world, and that who is the greatest BEAST of all is up for depate. (I know who get's my vote). (There is also a BEAST featured in the movie 'Fall of a Dream' from the Karen and Sam series)
