To get primed is the result of a member of the notorious Gang called Prime using a Kiddy Booter to hit you offline so you can no longer fight cartels on OG Moonshine
A primed cannon is when a man's penis is erect and sticking out of the fly/waistband of his underwear/pants, but his balls are not. Can almost be considered the opposite of pitching a tent.
The primed cannon sticks out of the ship, but the balls and seamen are safely stowed inside.
