from what I can gather from a quick search on the internet it seems he needed to pee while on the way to the rocket, so he stopped the bus bringing him there and peed on the tire of the bus. haven't really found any super reliable sources about this, though, and nothing about self urination

If my memory serves, I learned about this in astronaut Scott Kelly's autobiography:

Peeing on the bus tire became a sacred tradition, and Scott did it when he launched from that site.
