An often unsatisfying dump which, as a result of inadequate hydration, lacks the necessary bonding agent to form a large gratifying crap, and usually takes the shape of a pyramid in a mass of individual turds on the bottom of the toilet.
I just made a pile of cannon balls in there! Probably because I had a few beers last night, and ran a 5K this morning. .. I was so dehydrated.
A balls cannon is delivered by dropping one's trousers to moon someone, bending over far enough that the testicles become visible, waving the testicles at the recipient(s) with the hand, and shouting 'Baaalllllssss!'
The balls cannon can necessarily only be performed by a man.
When you put both balls into a girls (or guy's, we don't judge) asshole and s/he farts them back out. A satisfactory "pop" can be heard if done correctly
Taking a hit of weed, throwing down a shot of hard liquor, and then exhaling your hit. A crowd of people will usually yell "CANNON BALL" while you are in process of taking this shot. Please be warned....this could lead to a very rough night. But in the end, you will be CRUNK! If using Tequilla, it is recommended that you appoligize to all those around you in advance as you will make a scene.
Mark takes a huge hit off the blunt, slams a shot of Tequilla, then exhales and pounds his chest. (In the background, the whole party is yelling CANNON BALL)
