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.

Get the Butt Cannon mug.
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!!!!"
