fart cannon 

A disproportionately large muffler or exhaust pipe, mounted on an automobile with a small displacement engine. Named for the flatulence like sound the vehicle's exhaust makes.

A six inch fart cannon attached to a 1 inch tailpipe? Don't tell me. You've seen The Fast and the Furious at least once, right?

cannoñata 

From the now-defunct TV series, "Viva Piñata": The cannoñata (pronounced as though it were spelled, "cannonada") is a fictional device designed to shoot piñatas to piñata parties from its location (Piñata Central aka. Party Central, in very close proximity to the candiosity meter) on picturesque Piñata Island.

{Langston Lickatoad}: Get over here Fergy, time to get your candiosity checked and get you loaded into the cannoñata!

Chillicothe Cannon Ball 

When you put both balls into a girls (or guy's, we don't judge) asshole and s/he farts them back out. A satisfactory "pop" can be heard if done correctly

Glass Cannon Critic 

Someone who has no issue criticizing others, often to an extreme extent, but gets extremely defensive when he is under criticism.

He’s a glass cannon critic, which is why we hate him.

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.".

wow cannon 

The act of filling the end of a straw or other tube with cocaine and blowing it up the nose of a sleeping victim, timing it with the inhale.

Jimmy passed out during the dubstep pillow fight, so we hit him with a wow cannon. Then he raged feathers.
