The expression "pair off" means when two people or things come together and form a pair or a team. It is usually used when people are forming groups or teams or when two people are deciding to work together. For example, if you are in a class and the teacher asks everyone to pair off, it means that you should find one other person and work with them. Or, if you are playing a game and need to choose teams, you might say "let's pair off and choose our partners."
