cannonball 

A "dive" in which you hold your knees to your chest and hit the water with your fat ass with as much force as possible with the purpose of creating a gigantic splash, thus soaking everyone in the near vicinity.

That cannonball your mother just performed strangely reminded me of the movie "Deep Impact".

cannonball 

The term cannonball was first used by Carl Kearney Spackler (Bill Murray) in the masterpiece film Caddyshack. To do a cannonball you must first fill your lungs with weed smoke, while holding the smoke in you drink liquor. Preferably Johnnie Black. And take big swig not a little pussy shot. Then exhale. Say "Cannonball" and pass the bong and Johnnie black to your boy n-word Drew and repeat until liquor is finished (nobone in their right mind would ever run out of weed.) The best time for cannonballs is wednesdays at 10:30 during the Chappelle show. The best mix for this is Johnnie Black and Sour Diesel from the wiseman, Veil.

After I Kobed her I took a few cannnballs.

Cannonball 

A Cannonball is the act of indulging in one drug or alcohol then taking more right on top of that. It is not nearly as specific as most definers make it seem. Any time you use a drug or alcohol in rapid succession or simultaneously it can be considered a Cannonball. Even food can be cannonballed when you are eating your desert and scoop up some of your neighbors desert for a CANNONBALL!

Oh shit, Emily just cannonballed a Xanax bar on top of that suboxone!
Hey Mikey, cannonball that Patron' shot on top of that bowl you're smoking!
