Meat Cannon
A large slab of cock. Usually a long tubed sexual howitzer of lust accompanied with an undercarriage.
As she pulled the lanyard on my meat cannon, I drenched her face with my gooey gobs of banana juice.
Seaman's Meat Cannon
5 men slowing inserting there penises into a female's mouth. Before they cum they each pull out and shoot there cum in the woman's mouth and yell "Fire in the hole", each shoot there load into the girls mouth.
Dude last night this girl was so fucked up these guys gave her the old fashion "Seaman's Meat Cannon". She later died that night of breathing problems because of all that cum stuck in her throat.
