butt canyon

The area between the butt cheeks of a fat man. When you stare into this area, you get disgusted or amazed at the amount of vast area.

His butt canyon was the largest I have ever seen.

Butt Cannon

Is when you sit on the toilet, give one good push and you are instantly done. All the shit comes out at once. Sometimes it could be painful, others enjoyable.

Vacuum Butt Cannon

A fighting move in the sport of Keijo. Performed by spinning your hips and gaining a large amount of momentum, then jumping in the air and whipping them the other direction. This causes a massive rush of air directly towards the opponent, which if not dodged properly, sends them flying off the land (platform people play keijo on)

"Dammit, I'm about to fall off the land...
Time to use...
VACUUM BUTT CANNON!!!!"
