poo boom 

When you fart at such high speed you shit yourself and make a noise about it

After flatuating Barry realised he had poo boomed

Poo-boom 

When one unexpectedly experiences abdominal pain that results in one knowing that a shart is imminent so it is held in until an explosive situation happens on the toilet.

For example, after Steve got back to his desk in the cubicle he said to his friend, Mark, "Dude, I held in a shart and then...poo-boom all hell broke loose on the toilet."

Boomerang Poo 

Really floaty poo that when you try to flush it comes back.

Darling I've had the worst case of boomerang poo today. I flushed seven times and it's still floating in the toilet.
