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."

Get the Kung Fu Poomug. When you go for a poo and the weight and velocity causes it to a round the bend and escape the bowl. On top of that a true secret agent is when this happens that when you wipe your ass there is no poo on the tissue, it’s litterally so clean you could blow your nose on it. This is a true secret agent poo.
Wow it’s amaizing I never thought I would have a secret agent poo after that large mixed grill at spoons
