cannon 

A large calibre handgun that is much more powerful then what is necessary for self defense, and carried as a phallic symbol. Examples include the: .44 magnum, .45 ACP, .45 GAP, 454 Casull, 460 Remington, .50 AE, or a 50 SW.

I pulled my cannon, and fired six shots.

To Cannon or the practice of Cannoning is associated with the specific and highly regarded skill of hitting or cannoning a ball, while running at full speed. The ball would preferably be moving at a rate of knots at the time, however in exceptional cases (Alex, free kick, Chelsea vs Liverpool) a static ball is allowed.

The Cannon is a underused art in most professional sport, however it is slowly being reintroduced by purists of the game, it is now most commonly found in hockey at it highest level. Hockey allows the ball to be hit in a constantly rising trajectory until it is stopped only by the net.

Jesus Christ, he's just unleashed a Cannon

Cannon
When someone is dissed so bad to the point that to make them feel better is by humiliating them even more. This term is an NYC term to draw attention to the victim and in fact making the victim feel even worst than before. You must also yell the word cannon otherwise it won't be used in the correct sense.

Person A: Yo tasha never called me back son....gave her my number three weeks ago

When dumb people are describing 'canon', (the material accepted as officially part of the story in an individual universe of that story) they refer to it as 'cannon'.

Dave: Is that in the original story?
Mark: Just deal with it, it's cannon
Dave: You mean canon?
Mark: No I mean cannon! Boom!
Dave: *shakes his head*
