When someone's gas smells like old rotten trash. It is a distinct smell unlike other farts ie. eggfarts, dairyfarts, shitfarts. You literally can smell something rotting away in the culprits intestines. Sometimes, it requires intervention with a shop-vac.
Dude! That was a rancid trashfart! Go check your drawers!
