When a man farts while sitting on a nonporous (usually leather) seat and the gas expanding from his anus rapidly pushes his nuts forward, approximating the behavior of a pneumatic piston or cannon. Frequently catalyzed by the presence of tight pants and/or sweaty ass/thighs.
Dude, it was so hot this morning I was cannonballing all the way to work in the old Caddy. Gotta get me some cloth seats, or stop eating fuckin' breakfast burritos.

When someone intentionally fucks up another person's chances because of laziness or out of self-interest.
The head-hunter cannonballed my job application because she couldn't trust that I would stay in the position for more than 3 months conflicting with her company policy.

When a man is receiving oral sex from their boyfriend/girlfriend, they take their balls and put one on each side of the shaft so that it looks like a Cannon on rolling wheels. As the man approaches orgasm he announces that he is going to fire the cannon and forces the other party (Male or female) to deepthroat them and then the man takes a lighter and lights one of his pubic hairs one fire so that it begins to burn away. This must be timed correctly so that when the pubic hair is completely burnt away the man orgasms down the others throat (Like a cannonball firing)
I went home last night and decided to try something new on my girlfriend. She was giving me head and I Cannonballed her! She couldn't breath for 10 minutes! You should trying Cannonballing sometime man.
