shot the cat 

A fart so loud a deadly, you must down your pants or lifting the bed sheets to let it escape. Not doing so will result in your pants or bed heating so hot you will die from heat stroke.

"lucky i shot the cat this morning, or i would still be peeling the sheets of the roof"

took off like a cat shot in the ass 

To move very quickly.

When Jacky saw that spider she took off like a cat shot in the ass!
