At a large out door festival in the beer gardens. The mens washroom has a trough style urinal on both sides.

Well it had rained the night before and there was a lot of water on the floor mixed with piss, about an inch or two deep. It's was summer and I was wearing sandals, fortunately there was a dry path to navigate the washroom, that lead to an open clearing of urinal space and let me get there, dry footed.

So this guy walks in , giving zero fucks, sloshes through the piss water in sandals, whip out his pecker and starts going in the trough, standing about 10 feet away from me.

Then he passed out, on his feet, and fell straight back into the piss water. For a moment, he was just there, laying on his back, in 2 inches of urine, with his pecker still in his hand, still pissing, up and back down onto himself.

It was glorious.
