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.

Get the cannonballmug. 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.

Get the cannonballmug. When you hold your foreskin tightly with your dominant hand, and proceed to urinate within the sealed foreskin vicinity. Wait until maximum pressure is reached, and release upon shower-mates.
