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.

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.
