Guiness Fart 

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?"

Guinness fart

A Guinness Fart is almost the exact opposite to a genuine fart , and can catch you out after you have consumed a commendable volume of the lovely black liquid .
Having been lulled into a very false sense of safety and security by your own anus , you place your trust in it to release nothing but wind, but horror of horrors , it’s played a very cruel trick on you and will shoot out warm, black , stinking sticky bum treacle of a slightly thicker viscosity than what went in only a few hours beforehand . At this point and usually in the most inconvenient of locations, you have become a victim of a Guinness Fart

I’d only had 9 pints of Dublins finest and whilst walking home I trusted my sphincter to emit some gas which I thought had backed up inside my poop chute . How wrong I was, when the bastard sphincter tricked me with. Guinness Fart and deposited about 4 lbs of BumMolasses directly into my kex . To make matters worse , by the time I’d walked the rest of my journey , the dollop had went cold
