Shit Cannon 

While trying to poop, pushing and straining. The turd gives way and litteraly fires into the bowl and lets loose the "dammed" crap that was pressurizing the "cannon ball" and splashing the bowl water all onto the butthole.

Sorry about this morning babe, I didn't realize i had a shit cannon building up.

"...and once that cork let loose, (flatulant sounds)! Shitjust kept coming! Like I broke the shit dam and shit went all over the seat! It was sick!"
"why are you telling me about your Shit Cannon during our lunch break?"
"'cause the soup your eating looks like what I left for the Mrs. to clean up.".

Sphincterless Shit Cannon 

Someone who spends the majority of their workday clogging up the toilet and consistently smells like ass. Someone who who shits every hour on the hour, has no intestine, just a shit tube running from their throat to their ass, has been known to shit watermelons and small marsupials.

Man don't go into the bathroom, Jonathan has been acting like a Sphincterless Shit Cannon.

Human Shit Cannon 

when you shit so fast and hard you shatter the toilet bowl and create a moderately-sized hole in the floor below you

I became a Human Shit Cannon in the upstairs bathroom and spilled Grandma's ashes all over the living room floor with the impact.

SHIT BALL CANNON 

One of two definitions that will prove BULL SHIT is not appropriate for HOMO SAPIENS as either BALL SHIT or BOWL SHIT.

Take two plastic (MADE IN CHINA BALLS, big , purchased usually at your chain stores. SHOVE THE BALL in your ASSHOLE (preferably GO IN DRY as it will burn and hurt quite a bit as that is PEDOPHILE PUNISHMENT but after letting the first BALL get lost as the second BALL will become easier naturally and slide right in.

Well I see your ANUS has adjusted as I heard this explosion and saw the results of your SHIT BALL CANNON as your ASSHOLE accepted that second BALL and the BALLS flew out about thirty feet second one and first one ten feet and left a TRAIL OF SHIT tracing the trajectory of the two BALLS , your SHIT BALL CANNON as ANAL ALAN'S ASSHOLE strikes again.

cannon shit 

The art of shitting with so much force that it is as if a cannon is going off inside your ass, thus creating an explosion of shit.

"Bro I just took the heaviest shit out, it got onto the seat and the rim!"
"Fuck me, that's one hell of a cannon shit!"
