Horrible farts that jono does after drinking this vile, black oil.These are the worst farts known to man.

A fart produced after the consumption of much Guiness that is so foul and lethal to the nose that the drinking of Guiness may be prohibited by friends and loved ones.
"Fucking hell Ant, even you look disgusted by that one, no more Guiness for you. Guiness fart? Did you shit yourself?"
