Subway Slip-N-Slide
I went to undergrad about half an hour from New York City. The best way to get in and out of the city was via a train that went to Penn Station, which just so happened to stop running at around 1 AM. I asked a girl out on a date to see a concert in Brooklyn.
Everything was going well on the date itself, but the show was running long, so we had almost no chance of making the train. We still decided to try. We were transferring subways in a rush, flying down the stairs. I must not have noticed the puke on the steps, but it sure noticed me.
I wiped out about ten steps from the bottom, sliding on vomit the whole way down. I stood up immediately upon hitting the floor, but there was no salvaging this one or making it look intentional. My arms, legs, and back were pretty well-coated in vomit.
We stopped at a pharmacy to get antibacterial soap, but the puke on my clothing was not really removable. Then, we had to wait in deserted Manhattan for HOURS until the next train back, which was at around 7 AM the next morning. Story credit: Reddit / (dark_griever)
