the poof of poisonous gases that fester and brew and you hold in untill you find a victim to stand in front of in the grocery store and release your fart cloud upon them whilst you casually walk away and watch from the next isle as others look at them in disgust
that guy took so long in the grocery store selecting his brand of loo roll i just blew him a fart cloud within inches it smelt so bad other customers thought he had shat himself
A gaseous cloud of flatulence that is large enough to fully blanket a large city.
It was an astounding and ginormous fartcloud, one that was at least a thousand times larger than the largest clusterfart ever measured by fartologists.
