v. to fart so powerfully that a small, round turd shoots out of your butthole and instantly leaves a giant stain on the back of your pants ...unless it is unusually firm. in that case, it just makes a small hole in your trousers.

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.

A well trained road rallyist, who enjoys speeding on the open road. A driver with complete disregard for authority. A phrase made popular by Brock Yates, creator of the original "Cannonball Run" aka Cannonball Sea to Shining Sea Memorial Dash (1971).

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.

The nefarious and perverse act of standing a reasonable distance behind your doubled-over and unsuspecting partner, taking a run up and rifling your sack completely into her anus shouting "CANNONBALL!!!" at the last possible moment. Having knocked her to the ground with your scrotal barrage, proceed to jack off over her back while sitting balls deep on her ass and taunt her by singing shanties. Works best if she's just taken a shower because she'll be prepped, and then have to take another shower after you've demonstrated your pirate-like domination.
Theresa had just got out of the shower when Francois skidded round the corner and launched his nuts with hi-def explosive power into her rectal cavern, heroically crying "CANNONBALL!!!" and then nutted one out all up her back and in her hair. With his cannonballing mission complete, Francois knew the world was safe again.

When one is engaged in doggy style in the backseat of a moving vehicle with the windows down and finishes by slamming into their partner hard enough to force them through the window at a passing vehicle.
Guy #1: "Remember that time you cannonballized Ali?"
Guy #2: "I'm glad we weren't moving that fast when it happened."
