ass fumes

When you make a silent fart, sometimes, there will be a lingering smell. It will not go away quickly like a normal fart. It can smell like gas from the stove or it can smell like popcorn. Smells like it would be dangerous to light a match.

Is possible to occur after a loud, audible fart.

Oh, goddamn! Whoever farted released some gas-smelling ass fumes...

Man 2: what?
Man 1: A vile ass fume - *PRRRUT*
