Was out the other night and my friend came back from the bog in a club looking disgusted.

He'd been standing there having a perfectly innocent piss, when some lad suddenly ran in groaning in pain and pooed in the trough.

My mate had to finish his pee as this person's liquidy turds swam towards his stream.

The culprit was very apologetic. The cubicles were all being used. But what's more acceptable - turding yourself or turding in a urinal as someone is using it?
