An artillery piece, or something of that nature. I'm only writing this because I'm perturbed that the top definition for "cannon" is a misspelling of "canon." Are people really that stupid? I believe the answer is yes.
Canon is a totally different word than cannon.

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*

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
