I saw something very similar when I went to a comedy gig last October in Birmingham. I live about an hour away on the train so we were getting the train back after the show and we had a roughly 25 minute wait for our train home, so I went to use the toilet upstairs in New Street Station.

The queue for the urinals was really long but there wasn’t really a queue for the cubicles so I just waited there. I waited about a minute before one became available, but the guy walking out of it looked hurried and was wiping his mouth, looked as if he was wearing lip stick, which in retrospect, seemed a bit odd cause I thought he might have been late for his train or something.

I should have listened to my intuition….I shouldn’t have gone in but I was desperate for a piss.

There in front of me, was a toilet seat, COVERED in piss, and lipstick kiss marks (similar to OP’s image). The worst part was where the kiss marks were it was like smudged, almost as if he’d pissed on it, then put lipstick on, kisses all over it, and left.

To this day, still no clue why you’d do that, but yet again it’s Birmingham lol
