A hand cannon was the mother of all fire arms . It was simply a metal pipe that had gun powder put down it and a rock , or lead ball. It was fired by a piece of flaming rope put down in a open hole.

The best codename for a girl that you get a big boner for. Nobody will know what you mean, so feel free to express yourself in awkward ways!
Me: I have tried out the hand cannon that is totally from fortnite, and it is my favorite!

After a long night out, I decided to surprise my girlfriend in the morning, by blasting her through and through with my choades semen.Before she commented on the length, I blasted her between the eyes covering her forehead----knocking her back a few feet by the strength of my hand cannon (choade), ejaculation. The hand cannon is the situation, in which, a person as a choade but has a above average ejaculation strength, dubbed "The Hand Cannon."
