A few weeks ago, I was out on the piss, when I got halfway to the first pub and needed a slash. So, I nipped to where the public toilet was, about 20 metres away, but it was closed, so I preceded to urinate down the wall. Whilst there, I spotted a familiar shaped object, and it transpired that a tramp had had a shit there. It didn't smell at all. Until I pissed on it. I was pissing so much that I couldn't hold it and move, so I had to stay there for a full 90 seconds, breathing through my mouth. The stench was making me gag even breathing through my mouth, and smelt like a mix between shit, marmite and rotting flesh. My gag reflex was making me bob up and down whilst pissing, and I looked like an oversize fire extinguisher on a pogo stick. Finally I finished, and fucking sprinted away. I gagged all the way to the pub, couldn't even tell my mate what had happened due to the fact that thinking about it was making me gag. Anyone got any other smell horror stories?
