Wind off a stone

The purest and most potent chemical fart that a person can produce as a result of farting when needing to poo. Context: When you hold onto a brown monstrosity that is awaiting birthing, the godless ball of cursed sulphuric hell will persistently emit strong, disgraceful gas, whilst sitting in its forbidden fleshy purgatory. The gas must be exorcised immediately to avoid a sighting of the four brown horsemen, a documented sign of the impending aPoocalypse. The smell will resemble the inside of a large rotting Wildebeest corpse in summer and will risk the owner dangerously close to defecating themselves.
