[Best to start with an outline then. Not everyone was from a world that bothered with mass recreational entertainment. He takes a deep breath.]
A sport is a non-lethal and often heavily regulated physical competition between two teams or more of people, with the goal of entertainment for watchers. Teams must be identifiable at a distance for favorites to be cheered on by those same watchers, and often wear sleeveless colored tunics called 'sports jerseys'.
[Sports have their place but he can't ever be bothered with them.]
Everyone on a given team wears the same colors, but are differently numbered. If you see a white-shirted person with number 11 on them, they will have number 11 and be in a white shirt in every competition, so you can keep watching a favorite team member more than the rest. People get so caught up being enthusiastic for the team they like that riots and violence can and does break out when they lose. Or win, for that matter.
