Flatulence that is known to instantly clear the room. The smell of this fart will instantly burn your nose hairs and fry your brain cells. Fragrance very similar to a dead horse covered in flies or a Sulfur mine. Rotten eggs smell better than an atom fart, although they are somewhat comparable. Also known as an "Adam Fart".
Is that a dead rhino I smell? No man, that was just an atom fart.

The dude on the train ripped an atom fart that smells like a dead hooker covered in puke!

When Nicholas ripped that atom fart, it smelt like somebody was cooking 3 year old eggs with sulfur instead of salt.
