When you're forced to take a dump in a public restroom and you're just about to drop the bomb, when someone comes into the bathroom and tries to open the stall you're in! This cases the shit coming out your ass to suck back in and your meaty dump to be interrupted.
Man, I was taking a dump when this Turd Burgular came in and messed it up.
An animal, usually a dog, that "steals" a turd out of a cat's litter box . After this it eats it in all it's glory in another area of the home, resulting in bad breath, or "poop breath" and a big toothy grin.
"Wow, your dog's a turdburgular. He's chowin' on a huge turd from the catbox!"
