An act performed by the male where the genitalia is edged or grinded against extremely frequently, building up extreme pressure over days, weeks or even (daringly) months. This part is known as the "charging phase". Then comes the "sedentary" phase, where the male must not use his genetallia for at minimum, a week. This prepares it for the activation. With a single stroke, the build
up in sperm is all released at once, with hints of blood, sort of like the syrup and water mix at soda fountains. This act is very dangerous, as the piercing shot can easily rip through human skin and flesh.
The Canadian Cum Cannon is more common among word of mouth and folklore, not really reaching the bigger cities. For example, in the prairies it is known better as the Reginan Railgun. Make sure you're not
getting sloppy toppy either during the sedentary phase, you might lobotomize her. A ball usually gets sucked inwards back into your body, meaning you can only use this twice. Think of it as ammunition. Anything more than two will result in
instant death.
Person1: yo michael just hit
the Canadian Cum Cannon on his girl the other day. I wonder if he's good...
Person2: yeah those types of things are not for the faint of heart. I usually just stick with some of the tamer ones like the
Wisconsin Blow Dryer.
Person1: yeah you're right. I've got my own ready to launch right now but
I don't want to end up in the er like michael did from such intense pleasure all at once.
