Describe OR culture

I always read on these forums that one should only go into a surgical specialty if he/she enjoys OR culture and can really thrive in it. However, I don’t know what “OR culture” is. Could someone do his/her best to describe it for me? At least, describe his/her own personal experience with the OR and OR culture? Many thanks
