Pretty tame but a homeless dude at the front of the train, laying down on the seats, whips out his lil cock and starts streaming pee pee. Fountain-esque in trajectory, lots of pee. As the train moves, the pee moves towards the back of the train. When the train stops, the pee stops. It was like that game in Squid Games with the stop, go, stop, go. People were climbing on seats because as we bent around the track, the pee would swerve towards people. It never made it back to me and my SO. She wasn't happy that I wanted to stay on for 2 stops to watch before switching cars.
