Middle seat on a Transatlantic flight. You have some dodgy plane food, thrown up on the person sitting in the aisle seat and shart your squitty rancid **** all over the person sitting in the window seat. Their luggage is in the hold and they have to sit next to you in their putrid threads for the next 10 hours.
Remember being on a bus as a youngster and some bloke stood up to get off with a white tracksuit on and **** smeared down it. Everyone else was looking at each other in horror. Funnily enough I try to avoid public transport now where I can!
