1.Something you might call a friend, your boy, or someone you cool wit.
2.A tough mafucka or a hard rapper could be called a cannon too.

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

When a person attempts to make a "cannon ball" jump off a pier or diving board into a body of water while taking a dump at the same time.

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.

After space docking with a chick, you screw her abnormally hard in a position of your choosing. If you lasted more than a meager 5 minutes, the chick should be able to muster up a pretty nice quief. The turd which was loaded through the space docking procedure mentioned earlier, should be launched from her vagina like a cannon ball, just squishier. To achieve greater distance, you must "go the distance."

the act in wich a man lifts the legs of a pregnant woman till she looks like a cannon ball and proceeds to fuck her till he's satisfied or untill he pokes the babys face

when her pussy is so loose that you climb onto the dresser and cannon ball into it.
