Was out over the Christmas/New Year period and was outside in a line for one of a nightclub and desperately needed to piss and there was no way i could hold until i got inside ( the line was huge). So anyway, there was a back alley way just near where the queue had snaked. Not being able to hold any longer I darted down and found a dumpster and began relieving myself behind it.
Was mid way through when a copper walked past and saw me, and i was thinking oh **** this aint going to end well. Luckily however the bloke was in a similar position to me and came and stood behind this dumpster with me and relieved himself as well.
Fair to say not only did it feel great to empty the tank but also that I wasn't thrown in a divy van for performing a lewd act in public.
Did something similar after a game last year. Was pissed as a fart on the train on the way home. Got that bad I needed to piss. Felt like I was going to explode. What made it worse was I was on the train home - nowhere to go. The psychological feeling of no escape for easy relief made the pain tenfold. I thought I'd keep going and hold it. Got to a point where there was no way I was going to hold it. Do it or piss my pants. Me being drunk me, I got out when the train stopped at a station, with the intention of having a super quick piss then jumping back on. No way. So I'd got out at a station I'd never ever been to (this was about 11:30 at night mind you), and pissed all up the wall of the building. The piss travelled a good 100 metres all down the platform. Was going for a good minute or so I reckon. Put away so many beers and bourbons that night - the piss was thundering out. I zip up and walk back towards the front of the building and think "Oh, f*****g grouse", as there was a pack of either coppers or PSOs (can't remember, was too blind). Thought I was finished for sure. Instead, one of them must've seen that I was pretty wasted, so he asked "who won the footy tonight mate", then "by how much". Answered him and nothing more was said. Relief followed by relief.
